BMW E46 Reinforcement + Repair Part for Rear Control Arm Mounts

This set repairs and reinforces the rear control arm mount of the BMW E46, the spot where the rear trailing arm is attached to the body. On these cars, the metal around that pocket can rust through badly or crack. With these weld-in parts you rebuild the mount and reinforce it.

The set is made for demanding users and for E46 projects that serve as a base for motorsport. The best moment to tackle the rear control arm mount is during a build or an overhaul of the rear suspension, when everything is apart anyway.

Installation and delivery

This is a weld-in part. Before you cut anything away, place the supplied template against the body and drill a few holes as a reference. If those holes later line up exactly with the holes in the reinforcement, the part is in the right place. Because the pocket is larger than the original, you have to make room in the body with a few hammer blows.

Have the welding on the rear control arm mount done by an experienced welder and check the rear axle alignment afterwards. Treat the metal properly against rust after welding. For cars where the mount is still sound, also take a look at the reinforcement for the rear control arm mount of the E46, or browse all chassis and subframe reinforcements.

A rusted-through control arm mount is no reason to give up on an E46: with this set you rebuild it, reinforced.

Why choose this repair part for the rear control arm mount?

Welding in freehand repair plates takes a lot of time and rarely results in a neat, strong pocket. This set gives you a complete, pre-formed mount that you place in exactly the right spot with the template. The larger pocket also gives you more adjustment range for the toe straight away, which comes in handy on a lowered drift or grip car.

A sturdy rear control arm mount keeps the rear axle geometry stable, even under the heavy loads of drifting and track driving. That keeps the car predictable.

Frequently asked questions

Does this part have to be welded in?

Yes. The rear control arm mount is replaced or reinforced by welding the parts into the body.

What is the supplied template for?

Before cutting, you place the template against the body and drill a few reference holes. If those later line up with the holes in the reinforcement, it is in the right place.

Why do I have to make room with a hammer?

The pocket is larger than the original one, so that you can adjust the toe further. For that, the metal has to give way slightly.

What is the set for the rear control arm mount made of?

3 mm thick S355 steel, laser-cut and bent on CNC press brakes.

When is the best time to have this done?

During a build or an overhaul of the rear suspension, when the control arms are out anyway.
