[Mr.Fixit]

After driving lots of cobras with both 15" and 17" wheels, there is no comparison at all. The 17" wheel/tire setup performs so much better, all other aspects are secondary. Except looks and of course you can buy 17" tires with a good speed rating, unlike 15" tires. It's just that much more fun in corners, I sometimes take a cloverleaf offramp form the freeway, just to get back on a cloverleaf onramp. I love banked corners. However, I don't care for the "natural" center on PS wheels, you ought to polish or paint dark grey the centers. Make sure you get the right offset and tire size, it's no fun when the tires rub.
