Porsche 911 Turbo S 992.1 (2021–2025) Wheel Fitment Guide
The 2021-2025 Porsche 911 Turbo S 992.1 — covering the Turbo S Coupe and Turbo S Cabriolet — shares the wider 48mm-wider body of the 992 Turbo and is a completely separate fitment universe from the Carrera family. Unlike the Turbo, the Turbo S ships standard with centerlock wheels and PCCB ceramic brakes — the two most consequential differences for aftermarket wheel selection on this platform.
The standard delivery is the Turbo S Exclusive Design centerlock wheel: 9.5Jx20 ET44 front and 12Jx21 ET70 rear, with 255/35ZR20 and 315/30ZR21 tires. The Turbo S can be ordered with 5-lug wheels as a no-cost alternative at time of order. If your Turbo S has five individual lug bolts rather than a single central nut, the wheel dimensions are the same but the platform hardware and service protocol differ — see the OEM section for details.
The standard 420mm PCCB front calipers set the 20″ minimum for all Turbo S builds. Spacers are incompatible with the centerlock hub. The centerlock nut requires a calibrated centerlock torque tool at 600 Nm — standard impact wrenches will damage the nut. Platform hardware otherwise mirrors the Turbo: 5×130 bolt pattern, 71.6mm center bore, direct TPMS sensors, and rear-axle steering standard on all variants.
The 2025 911 Turbo 50 Years Edition is a limited-production variant of the 992.1 Turbo S — 1,974 units globally based on the 2025 Turbo S chassis. It uses unique Sport Classic Wheels in centerlock format with Brilliant Silver and White finish and is documented as a separate OEM configuration below.
About this guide: The fitment data below is compiled from owner-submitted builds and enthusiast forum research across Rennlist's 992 Turbo and Turbo S subforum and Planet-9. We summarize what 992.1 Turbo S 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.
Factory Wheel & Tire Configurations
The 992.1 Turbo S has one standard delivery configuration and one no-cost 5-lug alternative selected at time of order. Both use the same Turbo S Exclusive Design wheel dimensions in forged construction. The Turbo S is one of two 992.1 variants where PCCB ceramics are standard (the other is the GT3 RS) — this sets the 20″ front floor from the factory. A factory winter wheel package is also available for centerlock cars in narrower dimensions.
Aftermarket Wheel & Tire Configurations
All setups below are confirmed for the wider 992 Turbo body specifically. The Turbo S ships with the Exclusive Design wheel at ET44 front and ET70 rear — already more outward than the standard Turbo V Design — so the gap between OEM and flush is smaller here than on the base Turbo. Aftermarket fitments target the same OEM+ dimensional window, with progressively lower offsets bringing the wheel face flush with the Turbo S body and aggressive offsets pushing further outboard at stock ride height. 20″ is the hard minimum front diameter — the standard 420mm PCCB ceramics preclude 19″ fronts. Most documented Turbo S aftermarket builds are centerlock-specific wheels matching the standard centerlock hub; 5-lug Turbo S owners have access to the same offset configurations plus broader aftermarket choice.
Three constraints define the Turbo S fitment universe. First, the wider 48mm Turbo body means Carrera-family wheels do not fit — a Carrera S front wheel installed on a Turbo S body sits approximately 19mm past the fender. Second, the standard 420mm PCCB ceramic brakes (10-piston front, yellow calipers) require a minimum 20" front wheel — there is no 19" option on the Turbo S. Third, the standard centerlock hub is incompatible with wheel spacers, and the centerlock nut must be torqued to 600 Nm using a calibrated centerlock torque tool — standard impact wrenches will damage the nut profile. Direct TPMS sensors must be transferred or replaced when fitting aftermarket wheels.

What Happens When You Build With FMB?
The configurations above are a starting point — not a final spec. When you start your 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.
FAQ - Frequently Asked Questions
Centerlock is the standard default delivery on the 992.1 Turbo S — this is the opposite of the Turbo, which ships standard with 5-lug. The Turbo S can be ordered with 5-lug wheels as a no-cost alternative at the time of ordering. If your Turbo S has a single large central nut at the center of each wheel, it has centerlocks. If it has five individual lug bolts, it was ordered with the 5-lug option. The Turbo S Exclusive Design wheel is available in both centerlock and 5-lug formats with identical rim dimensions — the only difference is the hub interface.
Standard delivery is the Turbo S Exclusive Design in centerlock format: 9.5Jx20 ET44 front with 255/35ZR20 Pirelli P Zero tires, and 12Jx21 ET70 rear with 315/30ZR21 tires, in forged construction. Satin Black is the standard delivery finish; Platinum Silver and Aurum High Gloss are additional available finishes. The optional winter wheel package (centerlock) uses 8.5Jx20 ET40 front and 11Jx21 ET66 rear with 245/35R20 and 305/30R21 winter tires — narrower at both ends to accommodate the wider variety of winter tire sizes.
The 992.1 Turbo S ships standard with PCCB ceramic brakes: 10-piston 420mm front calipers (yellow) and 4-piston 390mm rear. These are the largest front calipers on any 992.1 variant — larger than the 6-piston 408mm calipers on the GTS and standard Turbo, and larger than the optional PCCB system on the Carrera S. The 420mm front rotors require a minimum 20″ front wheel. There is no 19″ front option on any Turbo S build. All flush and aggressive aftermarket setups in this guide clear the 420mm PCCB at 20″.
No. The Turbo S shares the wider 48mm Turbo body, which is a completely different fitment universe from the Carrera, GTS, and Carrera T. Carrera-family front wheels installed on a Turbo S body will protrude approximately 19mm past the fender. Turbo S wheels on a Carrera body will sit too tucked. Always confirm wheels are specced specifically for the Turbo/Turbo S chassis. The only wheels that cross-fit between the Turbo S and the Turbo are those in the Turbo S Exclusive Design family — both cars share the same 5×130 / 71.6mm CB hub and the same Exclusive Design wheel dimensions.
600 Nm / 444 lb-ft using a calibrated centerlock torque tool, per Porsche specification for all 992-generation centerlock wheels. Standard impact wrenches must never be used — impact force damages the anodized nut profile and prevents proper seating. The proper tooling includes the Porsche-approved centerlock tool and torque-multiplier setups rated to at least 600 Nm. Porsche specifies a programmed sequence: tighten to 600 Nm clockwise, reverse 60 degrees, then re-tighten to 600 Nm clockwise. For owners without proper equipment, installation and removal should be done at a Porsche service center or a shop with the correct tool.
No — wheel spacers are not compatible with the centerlock hub. The central nut seats directly against the wheel’s central bore through the hub spline interface — there is no flat mounting surface between hub and wheel for a spacer to occupy. The 5-lug Turbo S configuration can use spacers. For centerlock owners who want a more outward stance, the only path is aftermarket centerlock wheels with lower ET offsets manufactured to spec for the 992.1 Turbo S centerlock hub.
No — the Turbo S standard wheel is wider at both ends. The Turbo ships standard with the Turbo V Design: 9Jx20 ET41 front / 11.5Jx21 ET67 rear. The Turbo S ships standard with the Turbo S Exclusive Design: 9.5Jx20 ET44 front / 12Jx21 ET70 rear. The 0.5″ extra width front and rear on the Turbo S better fills the wheel well on the Turbo S chassis, which ships standard with PCCB ceramics and at a higher power level. A Turbo can be optioned with the Turbo S Exclusive Design wheel (in 5-lug format), making the two cars dimensionally equivalent when that upgrade is selected.
M14×1.5 lug bolts with R14 ball seat (spherical), 160 Nm / 118 lb-ft — identical to all other 992.1 5-lug variants. Most aftermarket wheels use a 60° conical seat. Always confirm your aftermarket wheel’s seat type before purchasing — running mismatched seat types prevents proper bolt seating and is a safety issue.
Rear-axle steering is standard on all 992.1 Turbo S variants. In practice, for aftermarket wheels designed for the Turbo platform, RAS does not present a fitment issue with any of the wheel sizes documented in this guide. Always confirm RAS clearance with the wheel manufacturer for unusual spoke profiles or narrow barrel geometries.
2021-2025 USDM. The 992.1 Turbo S launched for MY2021 (US deliveries late 2020). The 992.2 Turbo S launched for MY2026 with a T-Hybrid powertrain. Porsche confirmed in October 2024 that the current 911 Turbo S would continue for the 2025 model year unchanged before the hybridized 992.2 Turbo S launched for MY2026. Both the Turbo S Coupe and Turbo S Cabriolet are covered across the full 2021-2025 run. The 2025 911 Turbo 50 Years Edition (1,974 units globally) is also covered in this guide as a Limited Edition OEM card — it was based on the 2025 Turbo S chassis using unique Sport Classic Wheels. For the base Turbo, see the separate 992.1 Turbo Wheel Fitment Guide.
At stock ride height, the most commonly documented aftermarket setups on the 992.1 Turbo S are 20/21″ diameter staggered configurations targeting the Exclusive Design dimensions or progressively more outboard offsets. For flush stance: the 20×9.5 ET40 / 21×12 ET62 setup is the most widely documented flush configuration on Turbo S builds, often paired with 265/325 tires; the 20×9.5 ET44 / 21×12 ET66 setup is the conservative direct-fit option with OEM tire sizing; the 20×9.5 ET44 / 21×12 ET70 setup matches OEM Exclusive Design dimensions in aftermarket forged construction. For more aggressive stance: the 20×9.5 ET38 / 21×12 ET61 setup is documented with the wider 265/35-20 / 325/30-21 tire combination; the 20×9.5 ET35 / 21×12 ET60 setup is the most aggressive front offset commonly documented for stock-height Turbo S builds. All flush configurations are documented as bolt-on at stock height with no fender modifications. The aggressive configurations are documented at stock height by owners on stock SPASM, though some pair them with coilover suspension for cleaner appearance under compression. All configurations clear standard 420mm PCCB ceramics. There is no spacer-based path to outward stance on centerlock builds — all outward stance is achieved through aftermarket wheel offset selection.
The 2025 911 Turbo 50 Years Edition is a globally-limited 1,974-unit variant of the 992.1 Turbo S commemorating the 1974 launch of the original 911 Turbo (Type 930). Based on the 2025 Turbo S chassis, it uses unique Sport Classic Wheels in centerlock format with Brilliant Silver and White finish and center caps featuring the historic 1964-era Porsche Crest. The wheel dimensions are identical to the standard Turbo S Exclusive Design (9.5×20 ET44 front, 12×21 ET70 rear), so aftermarket fitment options align with the standard Turbo S configurations documented in this guide. The 50 Years Edition also receives additional standard equipment beyond the Turbo S: 10mm lower PASM sport suspension, front-axle lift system, sport exhaust with black tailpipes, tinted LED Matrix headlights, and black brake calipers. Available in centerlock only — no 5-lug option for this variant. Coupe only — no Cabriolet 50 Years variant.
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 hub configuration (centerlock vs 5-lug) and the 420mm PCCB ceramic brake clearance, and flags anything that falls outside what’s commonly documented on similar 992.1 Turbo S builds. We confirm centerlock hub compatibility, rear-axle steering clearance, and (on 5-lug configurations) R14 ball seat lug bolt geometry on every build. Second, our manufacturing partner verifies the wheel itself — backspace, brake caliper clearance for your specific brake package, centerlock hub fitment (or 5-lug seat type), 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. The 600 Nm centerlock nut torque procedure is yours and your installer’s responsibility on every wheel install — the proper centerlock torque tool is a non-negotiable part of CL ownership.
