i got some ground control springs/coilovers, but i kept my stock shocks. i have installed the rear springs, but dont know what to do about the front. the front springs are much smaller than stock (or the intrax ones i have). my friend has ground control on his e30 m3, and he said there was some cutting and welding involved in getting his on. is there any cutting or welding needed to get the fronts on, or is it just a straight change? thanks for the help, as i only have half my suspension done right now.
