BMW G87 M2 (2023-2026) Wheel Fitment Guide
The second-generation M2 — the G87 — shares its CLAR platform, S58 twin-turbo six, and most of its running gear with the G80 M3 and G82 M4. For wheel fitment purposes, that's the best news possible: the G87 runs the same 5×112 bolt pattern, 66.6mm hub, M14×1.25 conical-seat lug bolts, and 19" front / 20" rear factory staggered setup as its bigger siblings. What makes the G87 different — and better — is that the base car's 380mm iron front brakes are small enough to clear properly engineered 18" aftermarket wheels, which opens up track tire compounds and wheel weights that G80/G82 owners can't touch. This guide covers the base M2 (2023-2026), the 2026 M2 CS, the M Performance Parts forged accessory wheel, and documented aftermarket configurations from conservative flush to track-prepped aggressive.
About this guide: The fitment data below is compiled from owner-submitted builds and enthusiast forum research across the Bimmerpost G87 community, M3Post, and r/BMW. We summarize what G87 M2 owners have reported running successfully so you have a researched starting point for your build.
Every FMB build goes through a sanity check and an engineering verification before forging. We cross-reference the configuration you're ordering against your trim and brake package and what's commonly documented on similar builds — and our manufacturing partner verifies the wheel itself (backspace, brake caliper clearance, structural spec) before production begins.
Fitment decisions involving ride height, tire choice, and suspension setup are yours and your installer's call. Use this guide as research, not as a substitute for a real fitment conversation.

OEM Setups
Factory Wheel & Tire Configurations
BMW delivers the G87 M2 in the US market with a single standard wheel configuration throughout the 2023-2026 production run: Style 930M at 19×9.5 ET20 front / 20×10.5 ET20 rear. The 2025 model year refresh added a new bright silver finish option to the same wheel — the style number did not change. For customers wanting a forged wheel from BMW, Style 825M is available through the M Performance Parts catalog as a post-purchase dealer-installed accessory. The 2026 M2 CS ships with its own exclusive forged Style 827M wheel in matte Gold Bronze.

The standard wheel on every base M2 delivered in the US market. Jet Black is the default finish, with bi-color burnished available throughout the generation and a bright silver finish added for 2025+ cars. The 930M is meaningfully heavier than the forged wheels offered on the G80 M3 and G82 M4 at the same dimensions — the G87 received only cast wheels from the factory, which is commonly cited across Bimmerpost and M3Post threads as the reason aftermarket forged wheels have an outsized performance impact on this platform. Base M2 does not offer a carbon ceramic brake option, which means 18" aftermarket wheels are possible on this car — a significant advantage over the G80/G82 where 19" is the minimum.

Post-purchase accessory — not a standard delivery configuration on the G87 M2. Available through BMW dealers as a BMW M Performance Parts accessory, sold individually. Identical dimensions to the standard 930M wheel — same 19×9.5 ET20 front / 20×10.5 ET20 rear — so factory tires, lug bolts, and TPMS sensors all transfer directly with no modification required. The sole functional benefit is forged construction, which saves meaningful unsprung weight versus the standard cast 930M. Cross-platform compatibility with G80 M3 and G82/G83 M4 makes this wheel a common upgrade for M Performance Parts customers across the G8X family.

Standard equipment on the 2026 M2 CS — not available on base M2. The CS wheel contributes meaningfully to the CS package's 97-pound weight reduction versus the base M2 with Steptronic. Same 19×9.5 ET20 front / 20×10.5 ET20 rear dimensions as the standard 930M and accessory 825M, so aftermarket tire fitment data applies equally across all three OEM configurations. The matte Gold Bronze finish is exclusive to the CS — aftermarket copies of the 827M pattern are widely available but are not the genuine BMW M Performance product. The M2 CS is the only G87 trim offered with carbon ceramic brakes as an option, making it the only configuration where a 19" minimum diameter would apply.
Aftermarket Options
Aftermarket Wheel & Tire Configurations
The G87 M2 has the advantage of launching onto a platform that the aftermarket already understood — G80 M3 and G82 M4 wheel engineering cross-applies directly because they share the same 5×112 hub, same conical seat lug bolts, and same front suspension geometry. What the G87 adds to that is genuinely useful: the base car's 380mm iron front brakes allow 18" wheel diameters that the larger M3/M4 can't touch. This opens up track tire compounds, meaningful weight savings, and lower overall tire costs for owners who plan to push their M2 at the limit. The configurations below are organized by Square Setup and Staggered Setup — a structural decision that affects tire rotation behavior and visual character. Each card documents a configuration that G87 owners run, with sources tied to both vendor fitment documentation and named community builds.
Platform-specific fitment notes — G87 M2
Conical seat lug bolts — G8X family hardware.
The G87 uses factory M14×1.25 lug bolts with 60° conical seats, the same hardware spec used across the G8X family (G80 M3, G82/G83 M4). Aftermarket wheels designed for conical seat (60°) bolts are a direct hardware match. Wheels designed for ball seat applications require ball-seat lug bolts specific to those wheels — verify your wheel's seat type before sourcing aftermarket bolts. Whenever you add wheel spacers, longer bolts are required so thread engagement length matches stock plus spacer thickness.
Front fender liner clearance is the recurring constraint.
Vendor documentation and owner builds repeatedly cite front fender liner rub at full steering lock as the gating issue on wider front wheels and taller front tires. This is most often reported on 19×10 ET12 with 285/35R19, 20×10 ET8 with 285/30R20, 18×10.5 ET18 with 295/35R18 or wider, and 19×11 ET22 with wide-running tires. Shorter-sidewall variants (285/30R19 vs 285/35R19) are commonly cited as the practical mitigation.
18" brake clearance is possible but wheel-specific.
The base M2's 380mm iron M Compound front brakes are physically small enough that properly engineered 18" wheels clear them — but clearance is reported as extremely tight, with potential for debris damage to barrel or caliper, and risk of contact under hard track use. Spoke geometry matters as much as overall diameter. Do not assume any 18" wheel will clear; verify against the specific wheel's caliper clearance documentation. The M2 CS with optional M Carbon Ceramic brakes requires 19" minimum.
Aftermarket suspension can push spacer requirements.
Coilovers and aftermarket springs that reduce ride height also reduce inner wheel clearance to the strut and knuckle. Owners running aggressive square track setups (18×10.5 ET18, 19×10.5 ET18) on lowered suspensions commonly report needing wider front spacers than the vendor-recommended baseline. Plan suspension and wheel selection together rather than sequentially.

The conservative square fitment for the G87, frequently documented as a winter-wheel or all-season daily setup. Vendor fitment documentation lists this as a direct-fit configuration with no spacers required for clearance. Commonly paired tire options for winter use: Michelin Pilot Alpin PA4, Bridgestone Blizzak LM32, Continental WinterContact TS830P, Pirelli Winter Sottozero. For all-season summer use the 275/35R19 alternative provides slightly more contact patch without changing fitment behavior.

Square fitment at OEM diameter without dropping rim size. Commonly documented across G87 build threads as a balanced flush setup; vendor fitment guides list it as a direct-fit configuration. The wider 10" rim accepts the OE 275/35R19 tire size cleanly while widening the front track versus the stock 9.5J. Owners cite the practical benefits as reduced unsprung weight (forged versus the cast 930M), the ability to rotate tires front-to-rear to extend tire life, and improved understeer balance versus the staggered factory setup. Commonly paired tire options: Michelin Pilot Sport 4S, Continental ExtremeContact Sport, Yokohama Advan Apex V601, Goodyear Eagle F1 Supercar 3. Wider 285/35R19 alternative is documented but some front liner rub at full lock has been reported with wide-running tires.

The G87's signature track advantage over the G80/G82 — only possible on the base M2 with iron brakes. Documented in vendor fitment guides as the platform's primary 18" track configuration, and observed on owner track builds running slicks with substantial spacer stacks. Vendor guidance flags this as not a casual bolt-on: front brake caliper clearance is extremely tight at 18", and clearance is sensitive to spoke geometry — not every 18" wheel will clear. Adjustable camber plates are commonly recommended; aftermarket suspension may require additional front spacer beyond the vendor baseline. The payoff is meaningful unsprung weight reduction, access to 200-treadwear track tire compounds in 18" sizes that aren't readily available in OEM 19"/20" dimensions, and lower per-corner tire replacement cost. Commonly paired tire options: Falken Azenis RT660, Yokohama Advan A052, Bridgestone Potenza RE-71RS, Nitto NT01, Toyo Proxes R888R. The M2 CS with optional M Carbon Ceramic brakes cannot run 18".

The natural upgrade path for base M2 owners who want forged construction while preserving their factory tire investment. Documented across G87 build threads and listed in vendor fitment guides as an OE-tire-reuse configuration. The 19×10 ET12 front accommodates the factory 275/35R19 tire cleanly with the vendor noting it "easily fits"; the 20×11 ET18 rear reuses the factory 285/30R20, though vendor guidance flags that the OE tire is slightly stretched on an 11" rim. Bolt-on at stock ride height is the common reported outcome with no fender work required. Factory lug bolts, TPMS sensors, and tires all transfer directly. Vendor documentation notes some front rubbing can occur with tires that run wide at full steering lock — a known platform pattern, not specific to this configuration. Commonly paired tire upgrade options if not reusing OE: Michelin Pilot Sport 4S, Continental ExtremeContact Sport, Bridgestone Potenza Sport.

An OEM+ staggered configuration documented in vendor fitment guides as an SCCA street-class-legal setup. Front offset matches OEM at ET25; rear widens by 1" versus stock with a modest ET18 offset. Vendor guidance notes the 5mm front spacer commonly mentioned with this spec is for matching the factory front face position aesthetically — not required for brake or suspension clearance. Most 275/35R19 tires clear the front suspension without the spacer. Commonly paired tire options: Michelin Pilot Sport 4S, Continental ExtremeContact Sport 02, Bridgestone Potenza Sport, Michelin Pilot Sport All Season 4, Continental DWS06+. A documented entry path for owners who want forged construction and a wider rear contact patch without committing to a more aggressive face position.

A 20" staggered configuration that drops the front offset to ET18 and pairs it with a wider 20×11 ET25 rear, all on 275/30R20 + 305/30R20 tires. Documented on a 2024 M2 owner build via a vendor-hosted fitment gallery entry — running unknown lowering springs, reported as "Flush" with no rubbing, no spacers, and no modification required. The 20×10 front sits 2mm outboard of OEM in offset terms but the wider 10" rim contributes its own face-position outboard movement; the rear at 20×11 ET25 widens by 0.5" versus stock at a 5mm-inside-OEM offset. The more-aggressive face position in the same 20×10/20×11 + 275/30+305/30 family is documented on a 2025 M2 build at ET10/ET10 (see card later in this section). Compatible with both base M2 iron brakes and M2 CS optional carbon ceramic brakes; verify spoke clearance against your specific brake package. Commonly paired tire options: Michelin Pilot Sport 4S, Continental ExtremeContact Sport, Bridgestone Potenza Sport.

The taller-tire variant of the platform's 19×10 ET12 / 19×11 ET22 staggered pattern. Documented on a G87 owner build running Michelin Pilot Sport 4S at these dimensions. Front liner rub at full steering lock is the recurring platform concern at this combination — the taller 285/35R19 front tire sits closer to the inner liner than the shorter 285/30R19 alternative covered on the next card. Owners frequently cite this as a flush-aggressive daily setup that maintains 19" all around (preserving the option to run any G87-compatible tire size without diameter constraints) while delivering meaningfully more rear contact patch than the OE-tire-reuse configuration. Commonly paired tire options: Michelin Pilot Sport 4S, Continental ExtremeContact Sport, Pirelli P Zero.

The shorter-tire variant of the 19×10 ET12 / 19×11 ET22 pattern — frequently cited as the more clearance-friendly option. Documented across G87 owner threads with direct vendor-technical commentary in the source discussions: the wider-but-shorter tire heights are commonly explained as the practical reason this setup avoids the full-steering-lock liner contact that taller-tire variants can produce. The 305/30R19 rear is meaningfully wider than the OE 285 and delivers substantially more rear contact patch. Adjacent owner commentary on installed similar setups reports rear outside fender clearance is fine, with inner clearance closer — owners considering a 5mm rear spacer for appearance, not fitment. Commonly paired tire options: Michelin Pilot Sport 4S, Goodyear Eagle F1 Supercar 3, Continental ExtremeContact Sport, Bridgestone Potenza Sport.

The more-aggressive face position variant of the 20×10 / 20×11 family. Documented on a 2025 G87 M2 owner build via a vendor-hosted fitment gallery — running matched ET10 offsets front and rear on lowering springs, with 275/30R20 front and 305/30R20 rear tires, gallery-reported as "Flush, no rubbing" with no spacers and no modification. Same wheel diameter, width, and tire pairing as the preceding 20×10 ET18 / 20×11 ET25 card; differs in face position by 8mm front and 15mm rear, pushing the wheel face meaningfully outboard. Buyers comparing the two cards see the same wheel-spec family documented at two face positions on lowered G87 builds — the preceding card is the more conservative OEM-adjacent option, this card is the more aggressive flush option. Brake clearance is comfortable at 20" with no iron-vs-CCM constraint on the base M2; verify spoke clearance against your specific brake package. Commonly paired tire options: Michelin Pilot Sport 4S, Continental ExtremeContact Sport, Bridgestone Potenza Sport.

Documented with slight rub at full turn — not a clean bolt-on. A narrower-rim 20" staggered configuration using OEM-matched 9.5"/10.5" widths (vs the more common aftermarket 10"/11" widths on the G87) at meaningfully more outboard offsets. Documented on a 2023 G87 owner build via a vendor-hosted fitment gallery — running 20×9.5 ET8 / 20×10.5 ET10 with 285/30R20 + 295/30R20 tires on Eibach lowering springs, gallery-reported as "Nearly Flush" but with the owner specifically noting slight rub at full steering lock. The rub outcome is the buyer-relevant signal here: the OEM-matched rim widths don't compensate for the aggressive ET8 front face position when paired with a 285-section tire on a lowered car. Owners targeting this face position who want to avoid the rub commonly run a narrower 275-section front tire or accept the full-lock contact. Compatible with both base M2 iron brakes and M2 CS optional carbon ceramic brakes; verify spoke clearance against your specific brake package. Commonly paired tire options for narrower-front variants: Michelin Pilot Sport 4S, Continental ExtremeContact Sport, Bridgestone Potenza Sport.

The platform's primary appearance-focused 20" staggered configuration. Documented in vendor fitment guides as a staff-pick aggressive street setup and observed in G87 owner galleries on Michelin Pilot Sport 4S at these dimensions. The 20" diameter preserves the visual proportions of the wider G8X body and creates the most aggressive stance potential without dropping below daily-usable tire profiles. Vendor guidance notes front rubbing can occur with tires that run wide at full steering lock — the same platform pattern that affects most G87 wider-front configurations. Brake clearance is comfortable at 20" with no iron-vs-CCM constraint. The trade-off versus 18"/19" options is unsprung weight: 20" wheels and tires together weigh more than the 18" track-focused alternatives, so owners choosing this setup typically prioritize appearance over performance.

The most aggressive staggered configuration documented on the platform — a track-prepped build, not a bolt-on. Published at the effective face position; originally documented as 19×10.5 ET18 front + 5mm spacer / 19×11 ET22 rear + 12mm spacer, converted here to the direct-forged effective offsets. Documented on a G87 M2 owner build with substantial supporting hardware: AST HAS coilovers lowered approximately 1.5" all around, Millway Street camber plates, Frontline adjustable rear toe arms, and aggressive alignment (front camber approximately -3.5°, rear camber approximately -2.4°). Documented running Falken Azenis RT660 track-compound tires at 305/30R19 front and 315/30R19 rear. Owner reports the front did not rub but was "super tight" with planned clearance improvements; no rear fender rub over bumps. Vendor-technical commentary in the source thread advises monitoring full compression behavior. This configuration sets the upper bound of what the G87 has been documented to accept and should only be specced by owners with the suspension and alignment infrastructure to support it.
Our Process
What happens when you build with FMB
The configurations above are a starting point — not a final spec. When you start your G87 M2 build, here's what actually happens before anything is forged:
- FMB sanity check.
We cross-reference the configuration you're ordering against your trim and brake package — base M2 with iron M Compound front brakes, or M2 CS with optional M Carbon Ceramic — and compare it to what's commonly documented on similar G87 builds. If the setup you want falls outside what we've seen work on this platform, we'll flag it before you commit.
- Manufacturer engineering verification.
Our manufacturing partner verifies the wheel itself — backspace, brake caliper clearance for your specific brake package, and structural spec — before production begins.
- Design render approval.
You see the final design and confirmed specs before any aluminum is touched.
Ride height, tire choice, alignment, and suspension setup are variables your installer handles on the car — not things we verify from our end. That's why we ask for the vehicle details we do on the build form: they're the inputs we can actually check against.
Start your G87 M2 build →Common Questions
FAQ — Frequently Asked Questions
What wheels come stock on the G87 M2?
The base G87 M2 (2023-2026) ships with a single standard wheel configuration in the US market: Style 930M at 19×9.5 ET20 front / 20×10.5 ET20 rear, wrapped in Michelin Pilot Sport 4S tires sized 275/35ZR19 front and 285/30ZR20 rear. The 2025 model year refresh added a new bright silver finish option to the same wheel — the style number did not change. The 2026 M2 CS comes with its own exclusive forged Style 827M wheel in matte Gold Bronze at the same 9.5J x 19 / 10.5J x 20 dimensions. A forged Style 825M wheel is available as a post-purchase accessory through BMW M Performance Parts at the same dimensions.
What's the bolt pattern, center bore, and torque spec?
5×112 bolt pattern, 66.6mm center bore, M14×1.25 thread pitch, and 140 Nm / 103 lb-ft of torque. These specs are shared across the entire G8X M-car family — G87 M2, G80 M3, G82/G83 M4 — which means aftermarket wheels engineered for G80/G82 cross-apply directly to the G87 in hardware terms.
Will my factory lug bolts work with aftermarket wheels?
Usually yes, with verification. The G87 uses M14×1.25 lug bolts with 60° conical seats from the factory — the same hardware spec used across the G8X family (G80 M3, G82/G83 M4). Most aftermarket wheels are designed for conical seat (60°) bolts and are a direct hardware match. Some aftermarket wheels are designed for ball seat applications and will require ball-seat lug bolts specific to that wheel — installing the wrong seat type means the bolt won't seat correctly, can loosen under driving loads, and can damage the wheel or fail entirely. Confirm the seat type your aftermarket wheel requires before purchasing bolts. Whenever you add wheel spacers, longer bolts are also required so thread engagement length matches stock plus spacer thickness.
What's the difference between the base M2 and M2 CS wheel setup?
Dimensions and offsets are identical — both use 19×9.5 ET20 front / 20×10.5 ET20 rear with 275/35ZR19 / 285/30ZR20 tires. The differences are construction and finish: the base M2 gets Style 930M cast aluminum in Jet Black (or optional bi-color or silver), while the CS gets Style 827M forged aluminum in matte Gold Bronze. The CS wheels are exclusive to the CS trim and contribute meaningfully to the CS package's 97-pound weight reduction versus the base M2 with Steptronic. A second important difference: the M2 CS offers optional M Carbon Ceramic brakes ($8,500), while the base M2 is iron-only. This affects minimum wheel diameter — see the 18-inch question below.
Can I run 18-inch wheels on the G87 M2?
Yes — on the base M2, and this is a significant platform advantage over the G80 M3 and G82 M4. The base G87 M2's 380mm iron front brakes (M Compound) are small enough to clear properly engineered 18-inch aftermarket wheels. Vendor documentation confirms 18×10.5 ET18 as a documented G87 track configuration. The trade-off is that brake clearance at 18-inch is extremely tight and sensitive to spoke geometry — not every 18-inch wheel will clear, and even wheels that do clear may show debris damage or contact under hard track use. Benefits commonly cited by owners: meaningful weight savings versus the stock 930M, access to 200-treadwear track tire compounds that aren't readily available in OEM sizes, and substantially lower tire replacement costs. The M2 CS with optional M Carbon Ceramic brakes cannot run 18-inch.
What aftermarket wheels fit at stock ride height?
The G87's factory ET20 offsets sit close to flush already, so several aftermarket fitments are commonly documented as bolt-on at stock ride height. 19×10 ET12 square, 19×9.5 ET25 / 19×10.5 ET18 staggered, and 19×10 ET12 / 20×11 ET18 staggered with OE tire reuse are frequently documented as bolt-on with no fender work required. For 20×10/20×11 staggered configurations with 275/30 + 305/30 tires, two face positions are documented on lowered G87 builds: a 2024 build runs ET18/ET25 and a 2025 build runs the more-aggressive ET10/ET10, both gallery-reported as "Flush, no rubbing" on lowering springs. 19×10 ET12 / 19×11 ET22 with the shorter 285/30 + 305/30 tire combination is documented as bolt-on, with vendor-technical commentary explaining that the shorter sidewall avoids the full-steering-lock liner contact that taller-tire variants can produce. A 20×9.5 ET8 / 20×10.5 ET10 staggered with 285/30 + 295/30 is documented on Eibach lowering springs but with reported slight rub at full turn — buyers targeting that face position commonly run a narrower front tire (275 instead of 285) to avoid contact. More aggressive configurations like 18×10.5 ET18 square track setups and the most aggressive 19×10.5/19×11 305/315 staggered builds are committed builds requiring spacers, camber adjustment, suspension hardware, and in some cases liner work. Final fitment depends on your specific ride height, tire choice, and suspension setup.
Do I need wheel spacers?
It depends on your chosen fitment and suspension. At stock ride height on the documented bolt-on configurations (19×10 ET12 square, 19×10 ET12 / 20×11 ET18 staggered with OE tire reuse, 20×10 ET18 / 20×11 ET25 staggered with 275/30 + 305/30), spacers are typically not needed for clearance. Vendor fitment documentation flags spacers as appearance-driven on some configurations — for example, the 5mm front spacer commonly mentioned with the 19×9.5 ET25 / 19×10.5 ET18 staggered setup is for matching the factory front face position aesthetically, not for brake or suspension clearance. Track-oriented configurations (18×10.5 ET18 square, 19×10.5 ET18 square, 19×11 ET22 square) commonly require front spacers per vendor guidance, especially when running aftermarket suspension that reduces inner clearance. Whenever you add any spacer, install longer wheel bolts — bolt length must equal stock length plus spacer thickness for safe thread engagement.
Are the factory 930M wheels really heavier than the M3/M4 equivalents?
Yes — meaningfully so. This is commonly cited across Bimmerpost and M3Post as a distinctive G87 platform characteristic: the base M2 ships only with cast wheels and is significantly heavier than the forged M3 and M4 wheels offered in the same design at the same dimensions. BMW offered forged wheel options at multiple trim levels on the G80 M3 and G82 M4 from launch but did not extend that to the base G87. This is the single most common reason G87 owners upgrade to aftermarket forged wheels early in ownership — the weight delta is large enough that even a modest-offset aftermarket forged wheel produces noticeable gains in acceleration, braking feel, and steering response.
Do G80 M3 or G82 M4 wheels fit the G87 M2?
Physically yes — the G87, G80, and G82/G83 share the same 5×112 bolt pattern, 66.6mm center bore, M14×1.25 thread pitch, and 60° conical seat lug bolts. Hardware-wise, wheels engineered for the G80/G82 mount directly on the G87. Practically, body width is the caveat: the G80/G82 are wider cars than the G87, so aggressive aftermarket fitments engineered to fill G80/G82 fenders (deep-offset wider-rim staggered setups) may sit more aggressively or proud of fender on the narrower G87 body. Stock or near-stock-offset G80/G82 wheels typically transfer cleanly. Aftermarket wheels designed at G80/G82-specific offsets should be checked against G87 fitment data, not assumed to translate directly. The M Performance Parts Style 825M forged accessory is explicitly cross-platform compatible across all three (same dimensions on each).
Should I choose 18-inch, 19-inch, or 20-inch for aftermarket?
18-inch is the track and performance enthusiast choice — opens up 200-treadwear tire compounds, saves the most unsprung weight, lowers tire replacement cost, but only possible on the base M2 (not CS with carbon ceramic brakes) and requires verified brake clearance for the specific wheel. 19-inch is the versatility choice — maintains stock front diameter, allows reuse of factory tires on several documented configurations, widest range of aftermarket wheel designs available, and works on both base M2 and M2 CS regardless of brake package. 20-inch is the appearance-focused choice — preserves the visual proportions of the wider G8X body and creates the most aggressive stance potential, but adds weight compared to 18-inch and 19-inch options. For most daily-driven G87s, 19-inch square or staggered is the sweet spot. For tracked cars, 18-inch square. For show-and-street stance, 20-inch staggered.
How does FMB verify fitment before forging my wheels?
Every FMB order goes through a sanity check and an engineering verification before any aluminum is forged. First, our team cross-references the configuration you're ordering against your trim and brake package and flags anything that falls outside what's commonly documented on similar G87 M2 builds. Second, our manufacturing partner verifies the wheel itself — backspace, brake caliper clearance, and structural spec — before production begins. You then approve the final design render and confirmed specs before any work starts. Ride height, tire choice, and alignment are things your installer handles on the car; the fitment guides on this site are researched starting points for making those decisions with your installer.
