I bought some 17x9.5 C4 rims last year. They fit fine on the car, the offset is 5/16" different than my OEM 17x9's and of course they are 1/2" wider, which both of those things make them illegal in stock for Solo2.

Here is a picture:

Anyone out there willing to trade for legal 17x9 rims?

(no, the Hoosiers don't come with them)
