Stock sc4 offset I believe is 55mm. If you want to run 19X8.5 front depends on the wheels you can go from 36mm or 38mm offset up. For the Rear 19X10.5 is pretty hard to find the right offset that fit without rubbing or fender modification but it is do able. 19x9.5 is easier to fit with some offset like 38mm to 42mm.
