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
Most of the engineering value in a forged wheel over a cast one shows up in rotational mass, not outright strength — both can meet the same load rating, but the forged piece gets there lighter. On a sedan platform tuned for everyday balance, that weight saving is felt directly in steering response and ride quality.
The BMW M8 MotoGP Safety Car F92 ships from the factory on a 5x112 bolt pattern with a 66.6mm center bore and a F 20x9.5J ET28 / R 20x10.5J ET28 wheel. Our flush reference for the BMW M8 MotoGP Safety Car F92 is F 21x10J ET20 / R 21x11J ET22.; our maximum aggressive reference is F 21x10.5J ET15 / R 21x11.5J ET18. — beyond that, expect clearance issues against the fender liner without further modification.
BMW M8 MotoGP Safety Car OE Wheel Specs
The BMW M8 MotoGP Safety Car F92 ships from the factory on 5x112 bolt pattern wheels with a 66.6mm center bore. The stock wheel size is F 20x9.5J ET28 / R 20x10.5J ET28, 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.
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the BMW M8 MotoGP Safety Car F92 (2019) we drill the 5x112 pattern on our own CNC line, so the wheel hub-centres on the car with no spacer rings, in whatever diameter, width and offset you specify.

Flush Fitment
For a flush look without any body modification, most BMW M8 MotoGP Safety Car F92 owners run F 21x10J ET20 / R 21x11J 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 21x10.5J ET15 / R 21x11.5J ET18. KW V3 coilovers; 21x10.5J/21x11.5J BBS FI-R wheels; Carbon-Ceramic brakes; Michelin Pilot Sport Cup 2 tires. 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 20x9.5J ET28: backspacing ≈ 6.35"
- Flush 21x10J ET20: backspacing ≈ 6.29"
- Max 21x10.5J ET15: backspacing ≈ 6.34"

Custom Forged Wheels for the BMW M8 MotoGP Safety Car F92 (2019)
Everything above is reference data. If you want wheels actually built to it, that is what ANKUSI does: we are a forged wheel factory in Guangzhou, China, IATF 16949 and ISO 9001 certified, forging on our own 10,000-ton press and producing over 120,000 wheels a year. Forging blank, CNC machining, finishing, coating and inspection all happen in the same building — nothing is subcontracted and nothing is relabelled from another manufacturer.
Every set is cut to order, so the 5x112 pattern is machined for this car specifically. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose.

Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M14x1.25, 60-degree conical-seat lug bolt.
Factory Torque Spec: 140 Nm (103 ft-lb). Consistent across modern BMW passenger and X-series models using factory conical-seat bolts.
TPMS: TPMS (Tire Pressure Monitoring System) has been federally mandated on all new light vehicles sold in the US since the 2008 model year. If your wheels use OE-style sensors, have them transferred or cloned to the new wheels at installation.
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.
