I've searched all around and i can't find all the specs for the V2's wheels.

What i know

Front: 19x9.0 w/ 255/40-19

Rear: 19x9.5 w/ 285/35-19

Looking for

Offset: ?
Caliper Clearance: ?


Next, i know 20x10.0" wheels fit on the back of the CTS, anyone know or heard of someone that has wheels wider than that? Also i think a wider rim on the front won't work, but i am looking for any solid confirmation on this.

I have heard 10.5 fit in the back and 295 tires.

Also, does anyone know the GM part numbers for the OEM polished wheels?

Does anyone know this information?

I have tentatively found the offset to be 51mm in front 56mm in the rear.

A bump for anyone who can confirm this.
