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.
Mini JCW Anniversary Edition OE Wheel Specs
The 2021 Mini JCW Anniversary Edition (Limited Performance Hatch) uses a 5x112 bolt pattern with a 66.5mm center bore. Factory wheels are 18x8J at ET46.
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, 19x8.5J ET38 is the recommended starting point on a stock or mildly lowered Mini JCW Anniversary Edition.
Maximum Aggressive Fitment
19x9J 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: 18x8J ET46 → ~6.31″ backspacing
- Flush: 19x8.5J ET38 → ~6.25″ backspacing
- Max: 19x9J ET35 → ~6.38″ backspacing
A Note on Clearance
Final clearance depends on the exact tire model, suspension height, brake package, alignment and vehicle tolerances. A physical test fit is recommended before production.
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 Mini spec, or want a wheel built to a custom offset for your Mini JCW Anniversary Edition? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.
