Acura NSX NC1 (2017-2022) Wheel Fitment Guide

Not directly. The 2022 Type S OEM wheel uses a more negative offset than the standard NC1 Interwoven and Y-Spoke wheels — specifically calibrated to widen the front track 0.4″ and rear track 0.8″. Sharing identical 19/20″ diameter, 8.5J / 11J widths, 5×120 bolt pattern, and 70.1mm center bore, but the offset difference means a standard NC1 wheel installed on a Type S will sit further inboard than the factory Type S wheel, while a Type S wheel installed on a standard NC1 will sit further outboard. Owners moving between standard NC1 and Type S wheels commonly verify offset, tire diameter, and fender clearance before installation. The OEM tire specs are also different — standard NC1 came with Continental ContiSportContact 5P or 6, while Type S came with bespoke Pirelli P Zero “H0” rubber. Pirelli Trofeo R was available as an optional dealer-installed upgrade on both standard NC1 (refresh era 2019+) and Type S.

Bolt pattern: 5×120 (different from the first-generation NA1/NA2 NSX, which used 5×114.3). Center bore: 70.1mm (front and rear, unlike the first-gen which had split front 70.1mm / rear 64.1mm bores). Fastener type: Lug nuts on pressed-in studs (not lug bolts). Thread pitch: M14×1.5 (heavier than the first-gen’s M12×1.5). Seat type: Conical (60°). Torque spec: 170 N·m / 125 lb-ft (significantly higher than the first-gen’s 80 lb-ft due to the heavier thread spec). TPMS: Direct pressure sensors inside each wheel — must be transferred to aftermarket wheels or replaced. Tire pressure: 220 kPa / 32 psi front and rear. All specifications are identical across the 2017-2022 NC1 production run including the 2022 Type S.

The first-generation NSX (1991-2005, NA1 and NA2) and the second-generation NC1 (2017-2022) are completely different platforms with no wheel fitment crossover. First-gen used a 5×114.3 bolt pattern with M12×1.5 lug nuts, 80 lb-ft torque, and split front 70.1mm / rear 64.1mm center bores — meaning OEM first-gen wheels are NOT interchangeable with the second-gen even if dimensions match. The NC1 uses 5×120 with M14×1.5 lug nuts, 170 N·m / 125 lb-ft torque, and a uniform 70.1mm center bore front and rear. The two generations also use different OEM tire sizes and diameters — the first-gen ranged from 15/16″ through 17/17″ depending on year, while the NC1 is exclusively 19/20″ (or 20/21″ with documented upsize fitments). Owners cross-shopping wheels between the two generations should verify all hardware specs separately for each platform.

The NC1 uses conical (60°) seat lug nuts threaded onto pressed-in studs — the standard Honda/Acura configuration. Most aftermarket wheels designed for Japanese performance applications use 60° conical seats, so seat type matching is generally straightforward — but it’s still verified before installation because some aftermarket wheels designed for European platforms specify ball seat or other non-conical seat types. Running mismatched seat types causes point contact rather than full surface engagement, preventing proper wheel seating and potentially causing lug nuts to loosen under load. Before purchasing any aftermarket wheel for the NC1, confirm the wheel’s seat type and use matching M14×1.5 conical seat lug nuts. Many owners replace OEM lug nuts with aftermarket extended or open-end designs to accommodate aftermarket wheels with deeper lug seats — these are widely available in matching M14×1.5 thread.

Yes. The NC1 uses a direct TPMS system with physical pressure sensors inside each wheel. When swapping to aftermarket wheels, these sensors must be transferred from the OEM wheels to the new wheels or replaced with compatible sensors. Sensor transfer cost is typically $50-$150 per wheel depending on whether programming is included. After any sensor change, owners commonly recalibrate via the dashboard menu. The OEM sensors are designed to be transferable across multiple wheel sets, which is convenient for owners running separate summer and track wheel setups.

The NC1 standard brake configuration uses iron rotors at 370×32mm front with Brembo monoblock calipers — clearing both 19″ and 20″ wheel sizes documented on the platform. The 2022 Type S Lightweight Package added Brembo carbon ceramic brakes (CCB) at 15″ front rotor and 14.2″ rear rotor diameters with Brembo monoblock 6-piston front / 4-piston rear calipers — these are also the standard brake setup on the Type S Lightweight Package and are documented as cleared by the factory 19″ Type S wheels. CCB-equipped cars use larger calipers than the standard iron setup, so aftermarket wheels chosen for CCB cars need verification of inner barrel clearance against the larger caliper. Owners typically work with the wheel manufacturer to confirm CCB clearance specifically — the smaller NC1 community means fewer reference builds vs mainstream CCB platforms like Porsche PCCB.

170 N·m (125 lb-ft) for the OEM lug nuts, as specified in Acura’s accessory wheel installation document for the 2017+ NSX. This applies to both OEM and aftermarket wheels using the standard M14×1.5 lug nut hardware. Note: this is significantly higher than the first-generation NSX’s 80 lb-ft torque spec — owners cross-shopping hardware between generations should not assume the same torque values apply. Owners commonly retorque after the first 50-100 miles when installing new wheels to confirm proper seating. If performing a stud upgrade with aftermarket components, owners follow the torque specification provided by the stud manufacturer.

Mechanically yes — they share bolt pattern, center bore, and lug seat type, plus identical 19/20″ diameter and 8.5J / 11J widths. But the Type S OEM wheel uses a more negative offset that widens the track. Installing standard NC1 wheels on a Type S will result in the wheels sitting further inboard than the factory Type S spec — narrower track, more space inside the fender. Installing Type S wheels on a standard NC1 will result in the wheels sitting further outboard than the factory standard NC1 spec — wider track, less space inside the fender (potential rubbing on lowered cars). Many standard NC1 owners actually prefer the wider Type S stance and seek out used Type S wheels for the wider-track look. Type S owners typically retain their unique forged 5-spoke design due to its exclusivity and limited production. Verifying clearance against the specific brake package is the standard approach for cross-shopping between trims.

At stock ride height, the most commonly documented aftermarket setups on the NC1 NSX fall into two diameter categories. The OEM-diameter range stays at 19″ front / 20″ rear with offsets typically front ET43-ET55 / rear ET36-ET55 depending on whether the goal is OEM-correct stance or slightly more aggressive flush appearance. The 19×8.5 ET43 / 20×11 ET36 setup is the most widely documented OEM-replacement configuration — direct OEM dimensions with more flush offsets. The 19×8.5 ET55 / 20×11 ET55 setup reproduces exact OEM offset in lighter forged construction. The 20/21″ upsize range moves to 20×9 ET40-45 front with 21×12 ET40-50 rear, paired with 255/30-20 / 325/25-21 tires (Pirelli P Zero or Michelin Pilot Sport 4S documented in this sizing). All documented configurations are reported as bolt-on at stock ride height. Wider 20×9.5 / 21×12.5 setups are documented but typically require verification against specific brake package and ride height. The 2022 Type S sits slightly differently due to its wider-track OEM offset — Type S owners verifying aftermarket fitments calibrated for standard NC1 should expect slightly inboard placement vs the OEM Type S spec.

Every FMB build goes through two verification steps before anything is forged. First, our team runs a sanity check against your trim (standard NC1 vs 2022 Type S) and brake package (standard iron Brembo vs documented CCB), comparing it to what’s commonly documented on similar NC1 NSX builds. If something falls outside what we’ve seen work on this platform — the NC1 community is small and tightly tracked, so unusual configurations get flagged early — we tell you before moving forward. Second, our manufacturing partner verifies the wheel itself: backspace, brake caliper clearance for your specific brake package (iron or CCB), and structural spec. You see the final design render and confirmed specs before production begins. Ride height, tire choice, and alignment are variables your installer handles on the car — those aren’t things we verify from our end, which is why the build form asks for the vehicle details we can actually check against.
