I have heard that they are allright for normal driving, but not to race with them, just another thing to break. They should be easy to put on and take off, I would imagine atleast. there are some before and after shots on my link below. I don't know the backspacing on saleen wheels, But even from the side it looks better, and should handle better, with the wider stance. good luck, I would check out eibach or something first, and see what kind of guarantee they have.
