Among builds in our database for this model year:
1 documented build.
Documented on a 2012 Buick Regal build — observed custom fitment, not a universal fit guarantee.
Wheel: OEM Opel Insignia

OEM offsets are catalog configurations, not an aftermarket “safe ET range.” Matching offset alone does not confirm clearance. Documented custom builds are observed setups only.
