|---|---|
| Factory (OE) | F: 20x9.0J R: 20x10.0J |
| Flush Fitment | F 21x9.5J ET25 / R 21x10.5J ET30 |

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 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. 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 OE Wheel Specs
The 2020 Alfa Romeo Stelvio Quadrifoglio (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:
- Keeps the factory ride quality and noise levels intact
- A common fitment for this class, so replacement tires are easy to source
- Preserves clearance around the OE brakes and suspension geometry
- Delivers predictable, easy-to-live-with handling for daily use
ANKUSI builds these wheels — we are the forging factory, not a reseller. For the Alfa Romeo Stelvio Quadrifoglio (2020) we drill the 5x110 pattern and cut the centre bore to 65.1mm 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 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.
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? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
Custom Forged Wheels for the Alfa Romeo Stelvio Quadrifoglio (2020)
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 5x110 pattern and the 65.1mm centre bore are machined for this car specifically rather than shimmed with adaptor rings. Diameter, width, offset, concavity, monoblock or multi-piece construction and the finish are all yours to choose.
Designs we already tool for the 5x110 pattern — each one is re-cut to your sizes and offsets:
