I have done just about everything to my e28 535i. It's been lowered with eibach springs, has bilstein shocks, has new leather interior, 17 in. bbs wheels, new driveshaft, and a 750il front suspension. The next step is bumbper lipo. Ive seen it done before on other e28's and it looks great. Can someone please post how much this would probably cost? can a shop do it, or is it something you would want to do yourself? is there a site i can go to that gives detailed instructions on how to go about this? any help/info would be greatly appreciated, thanks
