I have e46 m3, and i installed pss9 coilovers and after riding on them for a few month i hear a slight metal scraping noise coming from my right side when i turn left quickly. Some body said it might be my rotors or brakes but i'm not sure if they know what there talking about. Has anybody experienced this problem. The car drives fine, but the weird thing is that it comes and goes. Can someone help me out.
