I have 17 racing dynamics on a 90 525. I also have billstein shocks all the way around. however i would like to improve the look and suspension of the car. Preferably, I would like the body to sit right on the wheel, with perhaps about a .3-.5 inch gap. The back is already low and I don't know if its weak springs or if the car just comes stock that way. If you have any suggestions, please email me at bhayada@hotmail.com, may be we can do some brain storming because i am building this car to be a competion car as far as looks go.
