BMW E46 Anti-Roll Bar Mount Reinforcement Rear Subframe

With this E46 anti-roll bar mount reinforcement you repair and strengthen the spot where the rear anti-roll bar is attached to the subframe of the BMW E46. A weak floor and rust on the rear subframe are well-known E46 ailments. A lot of force comes together precisely at the anti-roll bar mount, and that is where cracks then appear.

The kit is intended for powerful motorsport cars, for cars with a thicker anti-roll bar and for daily driven cars that have to endure weather and road salt all year round. You use it as a preventive measure or as a repair.

How do you recognise a problem? A clunking noise at the rear when turning in or going over speed bumps, or a car that feels unsettled at the rear in fast corners, can point to an anti-roll bar mount that has torn loose or cracked. Look under the car for hairline cracks and rust around the brackets on the subframe.

Installation and delivery

The reinforcement is welded onto the subframe, so welding is necessary. The most convenient time is when the rear subframe is out of the car, for example when replacing the subframe bushes or during a complete build. First take the steel around the mount back to bare metal and assess how far the damage goes.

Have the welding done by someone with experience in bodywork and chassis work. After welding, treat the subframe thoroughly against rust, with a primer and a tough top coat.

If the floor above the subframe is also weakened, take a look at the E46 reinforcement for the subframe floor. All reinforcements are in our chassis and subframe reinforcements category.

Weld it in properly once, and the anti-roll bar of your E46 has a mount it can rely on again.

Why choose this E46 anti-roll bar mount reinforcement?

You notice an anti-roll bar that tears loose straight away through an unsettled rear end. With the E46 anti-roll bar mount reinforcement you solve this structurally. The plates are bent to the shape of the subframe, so they fit neatly and the welding stays straightforward. The 3 mm S355 steel absorbs the forces where the original sheet metal gives up.

Frequently asked questions

Does the E46 anti-roll bar mount reinforcement have to be welded?

Yes, the plates are welded onto the rear subframe.

Can I also use the kit as a preventive measure?

Yes. The kit serves both to reinforce an intact mount and to repair a damaged one.

How thick is the steel?

3 mm, in S355 grade.

Is this necessary with a thicker anti-roll bar?

A thicker bar puts more force on the mount. That is exactly when a reinforcement is a sensible step.

Do the plates fit the subframe well?

Yes. The plates are shaped to the subframe around the anti-roll bar mount, so they sit tightly against the existing steel when you weld them in.

Does this kit fit an E36?

No, this kit is for the E46. We have a separate reinforcement for the E36.
