My 01 SLS was making noise in the front end, it sounded like I was running over a tin can. Also when I braked the car sounded like it was winding down, and a decent amount of steering wheel vibration. I took the car into my mechanic and had him check the cv joints and rest of the front end. He removed the drilled hole rotors the last owner had installed and replaced them and all the trouble I was having seems to be gone! Anyone ever have trouble with these type of rotors? My mechanic said they are not good for these type of cars.
