BMW M3 G80 (2021-2026) Wheel Fitment Guide
The G80 BMW M3 is one of the most fitment-specific performance sedans available today. Every OEM wheel — from the standard 824M through the optional 963M, the LCI-standard 825M, and the M3 CS-standard 827M — is forged aluminum at ET20, giving the platform a consistent offset foundation that makes sizing your aftermarket setup straightforward once you understand the constraints. This guide covers every USDM factory configuration across pre-LCI and LCI production years, documented aftermarket setups verified against named owner builds and vendor sources, Carbon Ceramic Brake clearance requirements, the front fender liner behavior that affects full-lock fitments, and the rolling diameter considerations that apply to xDrive cars running staggered setups.
About this guide: The fitment data below is compiled from owner-submitted builds and enthusiast forum research across Bimmerpost G80, M3Post, and Bimmerfest. We summarize what G80 M3 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
All G80 M3 models sold in the US share the same hardware: 5×112 bolt pattern, 66.6mm center bore, M14×1.25 lug bolts with 60° conical seats, torqued to 103 lb-ft. Every summer wheel available on this platform — from the base 824M through the optional 963M — is forged aluminum, an unusually premium baseline for a production sedan. The winter wheel 829M is the sole cast option. All OEM summer fitments are staggered: 9.5" width up front, 10.5" width in the rear, all at ET20.

Staggered setup: 19" front / 20" rear — identical dimensions and hardware to the 963M, but a distinct double-spoke design and not fully milled. The 825M became standard delivery on the 2025+ M3 LCI refresh (Bright Silver finish) and was offered as an optional upgrade from the base 824M on 2021-2024 pre-LCI cars. Available OEM finishes include Bright Silver, Orbit Grey matt, Jet Black diamond cut, and Satin Black. Approximately 2.5-3.1 lbs per wheel heavier than the 963M because the 963M is fully CNC-milled whereas the 825M is forged with standard finishing. Compatible with both factory steel brakes and factory Carbon Ceramic Brakes (CCB).

Staggered setup: 18" front / 19" rear. The 824M was the standard delivery wheel on all G80 M3 trims through the 2024 model year and is fully milled forged aluminum — an unusually premium base fitment for a production sedan. Compatible with factory steel brakes only; the larger Carbon Ceramic Brake (CCB) front rotors require a minimum 19" front wheel, so 824M-equipped cars cannot run CCB without changing wheels.

Slightly staggered winter setup: 19" front / 19" rear at narrower widths than the summer wheels (9.0" / 9.5" vs 9.5" / 10.5"). The 829M is the only cast aluminum wheel in the G80 M3 lineup, sold as a seasonal accessory through BMW dealers and developed with matched winter tires for the platform. Some owners run aftermarket square 19×9.5 ET20 winter setups instead, which simplifies rotation and broadens winter tire selection significantly.
Aftermarket Options
Aftermarket Wheel & Tire Configurations
The G80 M3's consistent ET20 offset across all OEM wheels gives a clear baseline: aftermarket wheels at or near ET20 in the factory 9.5"/10.5" widths are typically direct bolt-on. Moving wider or lower in offset is where the G80 starts to require attention — front fender liner clearance at full lock is the platform's most-discussed constraint, and Carbon Ceramic Brake-equipped cars carry tighter clearance requirements. 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 G80 owners run, with sources tied to both vendor fitment documentation and named community builds.
Platform-specific fitment notes — G80 M3
Front fender liner clearance.
Aggressive offsets at or below ET12 on 19-20" wide-body fitments can produce rubbing against front fender liners and cooling duct outlets at full steering lock, even at stock ride height. Any drop in ride height tightens this constraint. Trimming the front liner fins (commonly documented at about 50% trim) or running aftermarket replacement liners is the documented solution for fitments in this range. Owner builds at 19×10 ET12 with 285/35R19 tires specifically discuss this constraint.
Brake caliper clearance with CCB.
Cars equipped with Carbon Ceramic Brakes require a minimum 19" wheel diameter and tighter spoke-to-caliper clearance than steel brake cars. Confirm spoke-to-caliper clearance against your specific wheel design before committing — barrel geometry varies meaningfully by manufacturer and matters independently of offset. 18" track wheels are NOT compatible with CCB-equipped cars.
xDrive rolling diameter on staggered setups.
Staggered configurations can produce front-to-rear rolling diameter mismatches that may stress xDrive systems over time. Some aggressive aftermarket staggered setups (particularly those running a 305/30R20 rear) are vendor-published as RWD-oriented and not xDrive-compatible; alternative tire pairings are typically documented to bring the rear diameter closer to the front for xDrive viability. The math should be checked against your owner manual before committing — we document tire dimensions on every card; verifying compatibility is your responsibility.

The most frequently documented square flush setup on the G80 M3. The lower-than-OEM offset (ET12 vs ET20) pushes the wheel outward to fill the well evenly front and rear — the defining characteristic of a square flush fitment. Documented on cars running H&R Sport springs paired with Millway camber plates, with Hankook Ventus R-S4 track-compound tires for performance-street duty; owners typically report clean clearance at stock ride height without spacers or fender work. The 275/35R19 tire is the conservative tire choice for this offset — owners running 285/35R19 at the same wheel spec (see next card) typically report light contact at full steering lock against the front fender liner with certain tire compounds. Compatible with both factory steel brakes and CCB; spoke geometry should still be verified against your specific brake package. Commonly paired tire options: Michelin Pilot Sport 4S, Continental ExtremeContact Sport 02, Bridgestone Potenza Sport.

A conservative square setup more commonly documented in winter or all-season contexts than as a primary performance fitment. The ET25 offset sits just 5mm inside of OEM, producing a setup that's nearly invisible from stock at the wheel face but enables tire rotation between all four corners — a meaningful advantage for owners who want to extend tire life or run a single set of winter wheels. Commonly documented winter-tire pairings include Pirelli P Zero Winter and Michelin Pilot Alpin 5. Both factory steel brakes and CCB clear at this width and offset.

The aggressive tire variant of the platform's anchor square spec. Same 19×10 ET12 wheel as the Most Popular card above, with a wider 285/35R19 tire that increases contact patch and visual stance at the cost of front liner clearance at full lock. Owners running this spec on track-oriented builds commonly document trimming the front liner fins, running negative camber via Millway camber plates, and accepting occasional light contact at full lock in exchange for the more aggressive setup. Documented on cars running MSS Sport coilovers for street/track duty. Vendor documentation explicitly flags the rubbing-risk tradeoff with 285/35 vs 275/35 at this offset. Compatible with both factory steel brakes and CCB; spoke geometry should still be verified against your specific brake package. Commonly paired tire options: Bridgestone Potenza RE-71RS, Goodyear Eagle F1 SuperCar 3R, Toyo Proxes R888R.

A clean OEM+ flush staggered setup, with the front face matching OEM ET20 exactly and the rear pulled 2mm outboard via the ET18 offset. The 19" rear (vs OEM 20") slightly increases sidewall and changes rolling diameter — xDrive owners should verify against owner manual tolerance before committing. This is the OEM+ staggered fitment commonly documented across the G80 community and vendor fitment guides (originally published with a recommended 5mm front spacer producing an effective ET20 face position; FMB forges at ET20 directly so no spacer is required). Compatible with both factory steel brakes and CCB. Commonly paired tire options: Michelin Pilot Sport 4S, Continental ExtremeContact Sport 02, Bridgestone Potenza Sport, Toyo Proxes R888R.

A 20" staggered configuration documented on a 2023 M3 Competition xDrive owner build via a vendor-hosted fitment gallery — running 20×10 ET15 / 20×11 ET15 with 285/30R20 + 295/30R20 tires on Eibach lowering springs, reported as "Nearly Flush" with no rubbing, no trimming, and no spacers. The matched ET15 front-and-rear offsets produce a clean uniform face position on a lowered xDrive car; the 295 rear pairs with the 285 front to keep rolling diameter within xDrive tolerance. A documented variant of the same 20×10/20×11 wheel-spec family at the same 285+295 tires runs slightly more outboard at ET12 front / ET14 rear (see following card) on a stock-suspension build; an even more aggressive face position at ET10/ET10 with the same tires is documented further down. Compatible with both factory steel brakes and CCB; verify spoke clearance against your specific brake package. Commonly paired tire options: Michelin Pilot Sport 4S, Continental ExtremeContact Sport 02, Bridgestone Potenza Sport.

A 20" staggered configuration documented on a 2024 M3 Competition owner build via a vendor-hosted fitment gallery — running 20×10 ET15 / 20×11 ET22 with a narrower 275/30R20 front and wider 305/30R20 rear, on stock suspension, reported as "Flush Fitment on stock suspension" with no rubbing, no trimming, and no spacers. The narrower 275 front + wider 305 rear pairing is distinct from the 285+295 family that dominates the platform's 20×10/20×11 documented builds — it trades front contact patch for rear contact patch in a stance-oriented stock-suspension setup. The 305 rear puts rolling diameter outside typical xDrive tolerance, so this combination is RWD-oriented; xDrive owners wanting similar 20×10/20×11 face position should target the 285+295 family covered on adjacent cards. Compatible with both factory steel brakes and CCB; verify spoke clearance against your specific brake package. Commonly paired tire options: Michelin Pilot Sport 4S, Pirelli P Zero, Continental ExtremeContact Sport.

A 20" staggered configuration documented on a 2021 M3 Base owner build via a vendor-hosted fitment gallery — running 20×10 ET12 / 20×11 ET14 with 285/30R20 front and 295/30R20 rear tires. The same wheels at the same offsets are documented on a second 2021 M3 Base build running a wider 305/30R20 rear tire (same-wheel variant — buyers wanting a wider rear contact patch can target the 305/30R20 alternative, though that pushes rolling diameter further from a true xDrive-compatible pairing). The 20×10 ET12 front sits at the same outboard face position as the platform's anchor 19" square setup, so cars running aggressive front offset already know the front liner clearance behavior — full-lock contact at certain tire compounds is documented and resolved by aftermarket liners or fin trimming. Compatible with both factory steel brakes and CCB; verify spoke clearance against your specific brake package. Commonly paired tire options: Michelin Pilot Sport 4S, Continental ExtremeContact Sport 02, Bridgestone Potenza Sport.

The most-aggressive face position documented for the 20×10/20×11 family with 285/30R20 + 295/30R20 tires. Documented on a 2024 M3 Competition owner build via a vendor-hosted fitment gallery — running matched ET10 offsets front and rear on lowering springs. The same wheel-and-tire family is documented at more conservative face positions on adjacent cards (ET12/ET14 stock and ET15/ET15 on a lowered xDrive build), so this card represents the upper end of what owners have run with this wheel/tire combination. The matched ET10 front-and-rear offset pushes the wheel face meaningfully outboard relative to OEM ET20 — front liner full-lock contact at certain tire compounds is documented across the platform at this offset and is commonly resolved by aftermarket liners or fin trimming. Compatible with both factory steel brakes and CCB; verify spoke clearance against your specific brake package. Commonly paired tire options: Michelin Pilot Sport 4S, Continental ExtremeContact Sport 02, Bridgestone Potenza Sport.

NOT compatible with Carbon Ceramic Brakes — steel brake cars only. A specialized track and drag setup documented on G80 builds running KW V3 coilovers with Nitto NT01 track tires. Although the offsets differ by 5mm front to rear, this setup retains the same wheel diameter, width, and tire size across all four corners — meaning tires can be rotated front to rear like a true square setup. The 5mm front-to-rear offset difference reflects the documented per-axle clearance requirement (the front needs the ET13 face position to clear the spring perch with a 305-shoulder tire; the rear runs ET18 cleanly). This setup is the commonly documented vendor pattern for this fitment, originally published with a required 5mm front spacer that FMB eliminates by forging the front at ET13 directly. Trimming or replacing the front fender liner is commonly documented for this fitment. CCB-equipped cars require a minimum 19" wheel diameter — choose a 19" track setup instead. Commonly paired tire options: Nitto NT01, Toyo Proxes R888R, Toyo Proxes RR, Mickey Thompson ET Street.

A conservative 20" staggered show setup documented on a G80 build thread, derived from F90 M5-style aftermarket offsets adapted to the M3 platform. More OEM-adjacent than the aggressive 20" stagger options below — the higher offsets keep the wheel face closer to OEM position while the 20" diameter delivers the show stance. Owner-documented running 285/30R20 + 295/30R20 with a small front spacer for stance fine-tuning. The 295 rear keeps rolling diameter closer to the 285 front than a 305 rear would, making this the more xDrive-friendly 20" staggered option. Compatible with both factory steel brakes and CCB.

An aggressive performance-street and track staggered setup with the front matching the 19×10 ET12 square spec and the rear stepped to 19×11 ET22. Documented across multiple G80 M3 builds including cars running Moton 1-way Race suspension with Fall-Line rear control arms and Yokohama Advan A052 track tires, and Michelin Pilot Sport 4S street/track applications with mild lowering. CCB clearance is confirmed at this front spec on owner builds equipped with factory Carbon Ceramic Brakes. The 285/35 + 295/35 tire pairing is vendor-documented as xDrive-compatible; the alternative 275/35 front variant is vendor-marked as non-xDrive due to a wider front-to-rear rolling diameter gap. Compatible with both factory steel brakes and CCB; spoke geometry should still be verified against your specific brake package. Commonly paired tire options: Michelin Pilot Sport 4S, Bridgestone Potenza RE-71R, Yokohama Advan A052.

An aggressive 19" front / 20" rear staggered setup combining the platform's anchor square front (19×10 ET12) with a wider 20×11 ET18 rear and a 305-section rear tire. Vendor-documented as RWD-oriented — the 305/30R20 rear produces a front-to-rear rolling diameter gap that vendor fitment guides flag as outside xDrive tolerance. xDrive owners running this wheel spec can swap the rear tire to 295/30R20, which is vendor-documented as xDrive-compatible at the same wheel dimensions. Compatible with both factory steel brakes and CCB; the deep-concave rear barrel design should be verified for spoke clearance against CCB rear rotors before committing. Owner builds documented on stock and lightly-lowered ride heights with this exact spec; reusing the OEM 285/305 tire combination from the 825M is also a documented bridge approach before stepping up to wider front tires.

The most aggressive 20" staggered setup commonly documented for the G80 platform — an all-20" stagger pairing 20×10 ET8 front with 20×11 ET18 rear. Documented across multiple owner builds via vendor-hosted fitment galleries on a range of trims (Base, Competition, CS) and production years (2023-2025), confirming this offset family as the platform's anchor aggressive 20" show spec. Vendor-documented as RWD-oriented — the 305/30R20 rear produces a front-to-rear rolling diameter gap that vendor fitment guides flag as outside xDrive tolerance. Front liner rubbing is commonly documented at this offset with wider tires, particularly at full steering lock — aftermarket liners or trimming the liner fins are the documented solutions. Best suited for show builds and dedicated RWD owners willing to accept the front liner attention. Compatible with both factory steel brakes and CCB; verify spoke clearance against your specific wheel design.

An aggressive 20" OEM+ staggered show pattern documented on G80 build threads using mesh-style multi-piece forged wheels in the classic motorsport mesh design tradition. The narrower-than-OEM widths (9.5" / 10.5" vs the 10" / 11" of more aggressive setups) paired with lower-than-OEM offsets push the wheel face significantly outboard while keeping inner clearance manageable. The 245/35R20 + 275/30R20 tire pairing keeps rolling diameter close to OEM for xDrive viability. More OEM-derived than the most-aggressive 20×10 / 20×11 stagger (see preceding card) while still landing firmly in show-build territory. Compatible with both factory steel brakes and CCB.
Our Process
What happens when you build with FMB
The configurations above are a starting point — not a final spec. When you start your G80 M3 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, and compare it to what's commonly documented on similar 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 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 G80 M3 build →Common Questions
FAQ — Frequently Asked Questions
What are the factory wheel specs on the G80 M3?
All G80 M3 models use a 5×112 bolt pattern and 66.6mm center bore. Every summer OEM wheel — the 824M, 963M, 825M, and 827M — is forged aluminum at ET20 across the board. The standard 824M (2021-2024) is a staggered 18×9.5 front / 19×10.5 rear setup on 275/40R18 and 285/35R19 tires. The 825M became standard on 2025+ LCI cars at 19×9.5 / 20×10.5 on 275/35R19 / 285/30R20 — same staggered dimensions as the optional 963M and the M3 CS-standard 827M.
What are the bolt pattern, center bore, and torque specs?
Bolt pattern is 5×112. Center bore is 66.6mm. The G80 M3 uses lug bolts (not lug nuts), M14×1.25 thread pitch, with a 60° conical seat. Torque spec is 103 lb-ft (140 Nm). Aftermarket wheels that use a conical seat are a direct swap; wheels with a ball seat require ball-seat lug bolts specific to that wheel.
What aftermarket wheel sizes are commonly documented on the G80 M3 at stock ride height?
The most frequently documented square setup is 19×10 ET12 with 275/35R19 all around — the platform's anchor spec, with both vendor fitment documentation and multiple named G80 owner builds confirming it as a daily-friendly clean fitment. The 285/35R19 tire variant at the same wheel spec is more aggressive (more visual stance, more contact patch) but produces light contact at full lock with certain tire compounds. For staggered, 19×9.5 ET20 front / 19×10.5 ET18 rear with a 275/285 tire pairing is documented as a clean OEM+ flush setup. For 20" staggered, four distinct documented configurations exist in the 20×10/20×11 family: a 2023 xDrive build on lowering springs runs ET15/ET15 with 285/30 + 295/30 tires, a 2024 build on stock suspension runs ET15/ET22 with the narrower 275/30 front + wider 305/30 rear pairing, a 2021 stock build runs ET12/ET14 with 285/30 + 295/30, and a 2024 lowered build runs the most-aggressive ET10/ET10 with the same 285+295 tires. At stock ride height, owners typically report these fit without fender work, though some tire compounds produce light contact at full steering lock against the front liner even on these sizes — aftermarket liners or fin trimming are commonly documented as the fix.
What's the difference between flush and aggressive fitment on the G80 M3?
Flush fitment on the G80 M3 means the tire sits level with or just inside the fender edge at stock ride height — commonly documented with offsets between ET15 and ET25 depending on width. Aggressive fitment means the tire face is at or slightly beyond the fender line, typically documented at ET12 or below on wider widths, and frequently requires aftermarket fender liners or trimming the front liner fins to manage full-lock clearance. Aggressive setups deliver more visual impact but require more attention to the front steering lock limit. The stance dots on each aftermarket card above map this spectrum visually — 1 dot is most conservative, 5 dots is most aggressive documented on the platform.
Do I need to worry about brake caliper clearance?
Yes — specifically for cars equipped with Carbon Ceramic Brakes (CCB). The factory CCB setup requires a minimum 19" wheel diameter; 18" wheels will not clear the larger CCB rotors. For cars with standard steel brakes, 18" wheels are compatible. Spoke geometry matters independently of offset — certain barrel profiles clear the steel brakes but are too tight for CCBs. Confirm spoke-to-caliper clearance with any wheel manufacturer before purchasing for a CCB-equipped car. If you want to run 18" track wheels (Nitto NT01, Toyo Proxes R888R, etc.), your car must have steel brakes — CCB-equipped cars are locked to 19"+ track setups.
Can I run a square setup on the G80 M3?
Yes. The G80 M3 supports square setups and many owners cite tire rotation (front-to-rear) as the primary advantage over a stagger. The 19×10 ET12 square is the most commonly documented flush square fitment — with 275/35R19 as the conservative tire choice for full-lock clearance and 285/35R19 as the more aggressive option. Square setups do slightly reduce the rear contact patch advantage that the factory stagger is designed to deliver, but for street and moderate track use the difference is minimal. A more conservative 19×9.5 ET25 square is also commonly documented in winter or all-season contexts where tire rotation flexibility is especially valuable.
How do RWD and xDrive fitments compare?
Wheel dimensions are identical — 5×112, 66.6mm center bore, ET20 OEM — on both drivetrains. The xDrive front suspension geometry does not reduce inner clearance relative to RWD in a way that changes the minimum documented offset. The setups listed in this guide are commonly documented on both RWD and xDrive builds where noted. The xDrive-specific consideration is rolling diameter on staggered setups — most aggressive 20" staggered setups (particularly those running a 305/30R20 rear) are vendor-published as RWD-oriented and not xDrive-compatible. xDrive owners running aggressive stagger commonly run a 295/30R20 rear instead, which brings rolling diameter back within tolerance. Each card documents tire dimensions; verifying the pairing falls within the AWD tolerance is the buyer's responsibility.
What about 18" track wheels for CCB-equipped cars?
Cars equipped with Carbon Ceramic Brakes cannot run 18" wheels — the CCB front rotor diameter requires a minimum 19" wheel for caliper clearance. This is a hard mechanical constraint, not a fitment guideline. If you have a CCB-equipped G80 M3 and want a track setup, you're committed to 19"+ wheels. Common documented CCB-compatible track choices include the 19×10 ET12 square with 285/35R19 (Bridgestone RE-71RS, Toyo Proxes R888R, Goodyear Eagle F1 SuperCar 3R) and the 19×10 ET12 / 19×11 ET22 staggered with 285/295 tires. Cars equipped with the standard M Compound steel brake package can run the documented 18×10.5 18" track setup with 305/35R18 tires (Nitto NT01, similar).
What about spacers on the G80 M3?
Spacers are commonly used on the G80 platform for fine-tuning offset, particularly with factory wheels to achieve a flush stance. The thread pitch is M14×1.25, and extended lug bolts are required with any spacer — bolt length must equal stock length plus spacer thickness for safe thread engagement. For custom forged aftermarket wheels, FMB delivers at the effective offset directly — the cards above show as-forged offsets, meaning a spec like the 19×9.5 ET20 / 19×10.5 ET18 staggered ships at those offsets without requiring a 5mm front spacer that some vendor-published versions of the same fitment recommend. This is a cleaner installation than running a higher-offset wheel with a spacer to achieve the same face position.
What are the best winter wheel options for the G80 M3?
BMW offers the factory 829M winter wheel (19×9 front / 19×9.5 rear, ET20, cast aluminum) specifically developed with matched winter tires for this platform — it is the only cast wheel in the G80 M3 wheel lineup. A common aftermarket alternative is a square 19×9.5 ET25 setup with 265/35R19 winter tires (Pirelli P Zero Winter, Michelin Pilot Alpin 5), which simplifies rotation and broadens winter tire selection significantly. Flow-formed wheels in this spec are commonly documented as the winter choice among owners not using the factory 829M.
Are M340i and G80 M3 wheels interchangeable?
Physically, yes — the G20 M340i and G80 M3 share the same 5×112 bolt pattern, 66.6mm center bore, M14×1.25 lug bolts, and 60° conical seat. M340i factory wheels (790M, 848M, 791M, 792M, 793i, 794M, 795M, 995M, 1038i) bolt to the G80 M3, and G80 M3 factory wheels (824M, 825M, 826M, 963M, 829M, 1000M, 827M) bolt to the M340i. The practical caveat: the M3 is wider in body and uses more aggressive offsets — most M3 aftermarket fitments push wheels further outboard than the narrower M340i body can accommodate without rubbing fenders. Stock M3 wheels generally fit the M340i; aggressive M3 aftermarket setups generally don't.
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 G80 M3 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.
