Chevrolet Corvette C8 Stingray OE Wheel Specs
The 2020 Chevrolet Corvette C8 Stingray (Coupe) uses a 5*120 bolt pattern with a 66.9mm center bore. Factory wheels are F: 19x8.5J R: 20x11.0J.
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 20x9.0J ET42 / R 21x11.5J ET52 is the recommended starting point on a stock or mildly lowered Chevrolet Corvette C8 Stingray.
Maximum Aggressive Fitment
F 20x9.5J ET38 / R 21x12.0J ET48 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): 19x8.5J ET52 → ~6.8″ backspacing
- OE (R): 20x11.0J ET64 → ~8.52″ backspacing
- Flush (F): 20x9J ET42 → ~6.65″ backspacing
- Flush (R): 21x11.5J ET52 → ~8.3″ backspacing
- Max (F): 20x9.5J ET38 → ~6.75″ backspacing
- Max (R): 21x12J ET48 → ~8.39″ backspacing
