BMW E9X NM Performance Rear Trailing Arm Set

Because of worn or failing suspension bushings and control arms, it's likely your E9x 3 Series displays vague, imprecise steering feel and handling - characteristics entirely foreign to BMW's original intentions.

ECS offers genuine BMW and aftermarket Rear Control Arm Upgrade Kits for your car, with complete kits featuring all parts required for a thorough suspension refresh.

The M3/1M control arm kits add about .75 degrees of negative camber to the front for improved handling and tire wear.
