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
A sedan's wheel spec is a balance point the factory tuned between ride comfort, steering feel, and everyday durability. Forging lets us hold that same structural margin while cutting rotational mass, which is where most of the real-world benefit — quicker steering response, marginally better ride — actually comes from.
The Mini John Cooper Works Aceman ships from the factory on a 5x112 bolt pattern with a 66.6mm center bore and a 19x8J ET42 wheel. Our flush reference for the Mini John Cooper Works Aceman is 20x8.5J ET35.; our maximum aggressive reference is 20x9J ET32. — beyond that, expect clearance issues against the fender liner without further modification.
