My 2003 2.5i has the sport package (with sport springs). A friend has offered to give me a Z4 Eibach Pro kit he has never used. Is it worth installing? How much lower would it be? How much stiffer would it be?
15mm lower. however they are supposed to give better road holding and improved comfort compared to the sport springs. I am also thinking of that mod but i am worried going that low :?
