hi guys,
i lurked around the site a few times before but now its official. I'm looking to do the suspension on my 91 318is and i found an H&R race spring and billy sport shock setup. I believe the setup is for a 325is tho. now im pretty sure it'll work on my 318 no problem., but i just want to double check myself before i buy this etup and left with parts i can't use. so the question really is: can u use a 325is suspension setup on a 318is??? what are the differences besides spring rate?
