Seriously looking at a set of pre-owned RS97's for my C2S. Wheels were originally purchased for a C4....wheel and tire sizes as follows:

Front - 8.0 x 19” offset 46mm - 235/35-19

Rear - 11.0 x 19” offset 55mm - 305/30-19

Any insight on how these will fit my car would be greatly appreciated. Thanks in advance!

A-

 

looks like it should fit perfectly, I have a more aggressive offset on my rear wheels but my tires are 295's so you should be fine.

 

Yes I agree. Would be a bit further out than factory, like you are running small spacers all around.
Should look good.

 

they fit perfect - i have them
