How to Read Wheel Offset & Measurements
Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
ANKUSI Engineering Expert Advice
Convertibles lose some of the structural rigidity a fixed roof provides, which means the suspension and wheels end up doing more of the work to keep the chassis composed. A forged wheel keeps unsprung mass down without sacrificing the strength margin the factory built in — useful on a platform that's already managing extra flex.
The Nissan Fairlady Z Roadster ships from the factory on a 5x114.3 bolt pattern with a 66.1mm center bore and a F 18x8J ET30 / R 18x8.5J ET33 wheel. Our flush reference for the Nissan Fairlady Z Roadster is F 19x9.5J ET22 / R 19x10.5J ET22.; our maximum aggressive reference is F 19x10J ET15 / R 19x11J ET15. — beyond that, expect clearance issues against the fender liner without further modification.
Nissan Fairlady Z Roadster OE Wheel Specs
The Nissan Fairlady Z Roadster ships from the factory on 5x114.3 bolt pattern wheels with a 66.1mm center bore. The stock wheel size is F 18x8J ET30 / R 18x8.5J ET33, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:
- Balances ride comfort with steering response and highway efficiency.
- Wide tire and wheel availability at the factory diameter keeps replacement costs low.
- Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
- Guaranteed clearance against brake calipers and suspension components.
Flush Fitment
For a flush look without any body modification, most Nissan Fairlady Z Roadster owners run F 19x9.5J ET22 / R 19x10.5J ET22. This setup tucks the wheel face closer to the fender lip while staying within safe load and clearance limits.
Maximum Aggressive Fitment
Owners chasing a more aggressive stance push to F 19x10J ET15 / R 19x11J ET15. KW V3 coilovers; 19x9.5J/19x10.5J VOLK Racing TE37SL wheels; Brembo 4-piston BBK; Michelin Pilot Sport 4S tires. Note: Z33 convertible; added structural bracing requires specific exhaust clearance checks. Clearance should be verified before ordering, especially on lowered cars.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as: wheel width (in) / 2 + offset (mm) / 25.4 + 0.5.
- OE 18x8J ET30: backspacing ≈ 5.68"
- Flush 19x9.5J ET22: backspacing ≈ 6.12"
- Max 19x10J ET15: backspacing ≈ 6.09"

Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M12x1.25, conical-seat lug nut.
Factory Torque Spec: 103-122 Nm (76-90 ft-lb). Range covers most Nissan passenger cars and crossovers on M12x1.25 studs.
TPMS: Vehicles built before the 2008 model year were not federally required to carry factory TPMS in the US, though many manufacturers adopted it earlier; verify whether your specific build has TPMS before ordering sensor-compatible wheels.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
