Would like to completely swap out out wheels with someone who has a C4S with my C2S. Its a good deal for me if they fit because I get the wider rear wheel, but I'm worried if they will fit. Local Porsche dealer says they will, but I thought I read the offset was different. Searching hasn't landed me any clear answers.

Anyone know for sure?

 

Offset is different. Depends on what your definition of "fits" is. I wouldn't do it.

 

The offset is different. It would not look the same if it fit

 

Q:Will it physically fit?
A: Yes.

Q:Will it destroy the rear bumper by throwing rocks and debris all over the sides?
A:Yes.

Q: Don't mind painting your bumper every year?
A: Go for it.
