hi guys i just recently bought my 97 240 in june and im anxious to start modding it, i was going to get tein coilovers but since im new to the modding game i wanted to know would that be all i need? i was told i would need control arms etc. if so, what would be a good brand and set to buy? i dont want the car slammed cause i live in brooklyn n.y and the streets here are horrible plus it would be my daily driver, but i DO want it fairly close to being slammed. Any advice and choices on coilover brands would be greatly appreciated thank you.
