Do not mix platforms: a wheel forged for one Buick bolt pattern / center bore combination will not hub-center correctly on a different one, even if the diameter looks right. Always confirm your exact model and year against the bolt pattern and center bore listed on that model page below before ordering — or send us your VIN or trim level and we will confirm it for you.

Offset and backspacing recommendations vary by trim even within the same bolt pattern, mainly due to differences in brake caliper size and suspension geometry between base and performance trims. Every ANKUSI wheel is forged to your exact target offset, so send us your Buick model, year, and trim and we will confirm the correct spec before production — no guessing required.
