you obviously don't nee to change the studs, just make sure you have the type of wheels that allow the original studs on the car to stick through. I read of guys using some that require new studs, and the studs with the kit had knurling that was too long, and the brake rotors bottomed out on then instead of mounting flush to the hub. Definitely not good. I think project kics (rays engineering brand), or h&r are the best bet.
