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
SUVs carry more curb weight higher off the ground, so wheel strength and rotational mass both matter more than on a comparable sedan — a heavier wheel amplifies body roll and slows steering response exactly where the platform is already working hardest. Forging keeps the wheel light without giving up the load rating the factory suspension geometry was tuned around.
The Alfa Romeo Stelvio Quadrifoglio 100th runs a 5x110 bolt pattern, 65.1mm center bore, and a F: 20x9.0J wheel from the factory. Our Flush Fitment reference is F 21x9.5J ET25 / R 21x10.5J ET30, which tucks the tire under the fender lip on a stock-height Alfa Romeo Stelvio Quadrifoglio 100th. Our Maximum Aggressive reference is F 22x10.0J ET20 / R 22x11.0J ET25 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Alfa Romeo Stelvio Quadrifoglio 100th OE Wheel Specs
The 2023 Alfa Romeo Stelvio Quadrifoglio 100th (SUV) uses a 5x110 bolt pattern with a 65.1mm center bore. Factory wheels are F: 20x9.0J R: 20x10.0J.
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 21x9.5J ET25 / R 21x10.5J ET30 is the recommended starting point on a stock or mildly lowered Alfa Romeo Stelvio Quadrifoglio 100th.
Maximum Aggressive Fitment
F 22x10.0J ET20 / R 22x11.0J ET25 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 20x9.0J ET29 → ~6.14″ F backspacing, R 20x10.0J ET33 → ~6.8″ R backspacing
- Flush: F 21x9.5J ET25 → ~6.23″ F backspacing, R 21x10.5J ET30 → ~6.93″ R backspacing
- Max: F 22x10.0J ET20 → ~6.29″ F backspacing, R 22x11.0J ET25 → ~6.98″ 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 Alfa Romeo spec, or want a wheel built to a custom offset for your Alfa Romeo Stelvio Quadrifoglio 100th? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
