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
Every gram of rotational mass on a supercar fights the acceleration, braking, and rotational inertia numbers the factory spent enormous engineering effort achieving. A forged wheel for the Audi R8 Coupe Audi Sport Edition holds the OE strength rating at meaningfully less weight, which is a real, measurable performance gain rather than a cosmetic one.
The Audi R8 Coupe Audi Sport Edition runs a 5x112 bolt pattern, 57.1mm center bore, and a F: 20x8.5J wheel from the factory. Our Flush Fitment reference is F 20x9.0J ET35 / R 20x11.5J ET40, which tucks the tire under the fender lip on a stock-height Audi R8 Coupe Audi Sport Edition. Our Maximum Aggressive reference is F 21x9.5J ET30 / R 21x12.0J ET35 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Audi R8 Coupe Audi Sport Edition OE Wheel Specs
The 2017 Audi R8 Coupe Audi Sport Edition (Supercar) uses a 5x112 bolt pattern with a 57.1mm center bore. Factory wheels are F: 20x8.5J R: 20x11.0J.
Why the factory spec works for most owners:
- Balances ride comfort with everyday drivability
- A commonly used size for this vehicle class, supporting parts and tire availability
- Maintains clearance for the factory suspension and brake components
- Provides stable, predictable handling across normal driving conditions
Flush Fitment
For a flush look with minimal rubbing, F 20x9.0J ET35 / R 20x11.5J ET40 is the recommended starting point on a stock or mildly lowered Audi R8 Coupe Audi Sport Edition.
Maximum Aggressive Fitment
F 21x9.5J ET30 / R 21x12.0J ET35 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 20x8.5J ET42 → ~6.4″ F backspacing, R 20x11.0J ET50 → ~7.97″ R backspacing
- Flush: F 20x9.0J ET35 → ~6.38″ F backspacing, R 20x11.5J ET40 → ~7.82″ R backspacing
- Max: F 21x9.5J ET30 → ~6.43″ F backspacing, R 21x12.0J ET35 → ~7.88″ R backspacing
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Audi spec, or want a wheel built to a custom offset for your Audi R8 Coupe Audi Sport Edition? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.

Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M14x1.5, ball-seat lug bolt (13mm radius).
Factory Torque Spec: 120 Nm (89 ft-lb). Shared VW/Audi Group ball-seat bolt spec used across most 5x112 Audi models.
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.
