I want to replace the 17" wheels on my '01 C4 Cab with 18". I like the GT3 style. Will they fit? What are some good brand names if I can't get OEM. There are a lot on eBay but am not sure of the quality. Porsche salesman says I shouldn't replace the 17" with 18". Says I won't like the handling. Anybody have any experience with that? They were an option on that model year.

 

check the offset of the original and the potential new wheels. You want to make sure they will accomodate brakes etc.
