No problems at all. Maybe .2 secs slower but it's acceptable. My car is as fast as Scotts so may not lose any acceleration at all. Of all the people who have commented on my car I have had more compliments on the wheels than the car it's self.

Hey buddy! Question, do you have any regrets about the 21" rims? Weight issues,turning,acceleration etc.. btw im gonna order the same color combo and wheel package as yours!
