BMW E36 Rear Subframe Floor Reinforcement, Weld-in Kit

This E36 rear subframe floor reinforcement is a weld-in kit for the body floor at the spot where the rear subframe of the BMW E36 is mounted. That piece of sheet metal is a well-known weak spot of this model: with stiff suspension or sporty use, it cracks around the mounts or gets distorted.

For a drift car, racer or track day E36, the question is not if it will happen, but when. With these plates you repair existing damage and make sure the floor can handle the forces of the rear subframe from now on.

Installation and delivery

The plates are welded onto the floor, at the position of the rear subframe mounts. This is a job for an experienced welder. The subframe usually comes out so that you can get to the sheet metal properly. Have existing cracks professionally welded shut first, before the reinforcement plates go on.

Clean the floor around the mounts back to bare metal, on the inside of the car as well, and remove sealant and insulation material because of the fire risk. After welding, treat everything properly against rust, underneath and on the inside.

If the subframe is out anyway, this is also the moment to replace the subframe bushes. A tight subframe mounting combined with a reinforced floor gives a rear axle that does exactly what you expect.

Plan the job for a quiet period in the winter or between two events. With the car on the lift, the subframe out and a welder who knows what he is doing, the E36 rear subframe floor reinforcement is a manageable job. After that, the car can take it again for years.

You will find more reinforcements for the body in our chassis and subframe reinforcements category. If the upper rear shock absorber mount is also cracking on your E36, take a look at the rear shock absorber mount reinforcement.

Weld it in properly once and the well-known cracking problem at the rear subframe of your E36 is a thing of the past.

Why choose this E36 rear subframe floor reinforcement?

On the E36, the sheet metal around the rear subframe was not made for the forces of a drift car or a circuit car with stiff suspension. With these weld-in plates made of S235 steel, you spread those forces over a larger area. If you are building a project, fit them before the problems arise. That is much less work than repairing a cracked floor later.
