Thanks for the answers!
There is no way we put 17" wheels on the car. I prefer pay twice the price for the same tire in 15" than 17", but I really don't like Cobra's with 17" wheels. The only one I love is a grey Cobra with white lanes, and 17" Halibrand. It's for sale on pistonheads, for about 80-90000$.
