Wheel Size & Offset at a Glance
| Configuration | Wheel Size & Offset |
|---|---|

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
Coupes and performance platforms are where rotational mass shows up fastest — in acceleration, in braking, and in how quickly the chassis changes direction. Forging lets us build to the same strength spec as the factory wheel at a meaningfully lower rotational weight, which is where the performance gain actually comes from, not just the visual one.
The Audi RS5 Coupe Sport Edition runs a 5x112 bolt pattern, 66.5mm center bore, and a 20x9.5J, front and rear, wheel from the factory. Our Flush Fitment reference is 21x10.0J ET20, which tucks the tire under the fender lip on a stock-height Audi RS5 Coupe Sport Edition. Our Maximum Aggressive reference is 21x10.5J ET15 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Audi RS5 Coupe Sport Edition OE Wheel Specs
The 2015 Audi RS5 Coupe Sport Edition (Coupe) uses a 5x112 bolt pattern with a 66.5mm center bore. Factory wheels are 20x9.5J F/R.
Why the factory spec works for most owners:
- Keeps unsprung weight low to preserve the factory handling balance
- Matches the wider, performance-oriented tire sizing typical of this platform
- Maintains clearance for the factory brake package and suspension geometry
- Balances grip with ride comfort for daily and spirited driving
Flush Fitment
For a flush look with minimal rubbing, F/R 21x10.0J ET20 is the recommended starting point on a stock or mildly lowered Audi RS5 Coupe Sport Edition.
Maximum Aggressive Fitment
F/R 21x10.5J ET15 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: 20x9.5J ET25 → ~6.23″ backspacing
- Flush: 21x10.0J ET20 → ~6.29″ backspacing
- Max: 21x10.5J ET15 → ~6.34″ 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 RS5 Coupe 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.
