I've been searching forever for a set of affordable coilovers for my crossfire. I've only found the kw kit which is like $2k. I found another set by bc racing but they've been discontinued. So I've already ordered a set of rear camber adjustment arms for a R170 MB under confirmation from the manufacturer that they are the same part. So I've begun looking for coilover kits for the same R170 chassis and was amazed at the selection available. So the obvious question at hand is are they going to be compatible? I've tried contacting sellers of these kits and they haven't been of any real help. If the chassis code is the same between the two cars, then I don't see why they should use different suspension components. I plan on visiting my local MD Dealership in search of more information and should I come to any concrete conclusions I will post the information here. Please, if anyone has any real information and not just speculation or any actual experience in this matter, add to this post and help me with this matter. Thanks everyone
