New to this site...
I have a 2011 CTS 3.0 RWD and I'm looking to get some aftermarket rims/tires.
I searched around and didn't see much by way of OFFSET and different sizes.
Some guy offered me brand new Rims (18", 5x120, +20 Offset) and 225/40/ZR18 Tires.
Will these fit? Or will I need some sort of modifications?
Thanks for your help!
