[alfa11]

there are 11" wheels that will fit.

You may need to slightly alter the inner fender lip. There is a factory sheet on the modification.

The offset is critical.

I run 19"x11" rear BBS wheels on my 2004 C2.

I will say that If I were to do it again, I would go for the 10". I think the rears overwhelm the front a bit in the fast turns.
