Rear Chassis Reinforcement Plate Combo / E36

The rear half of the E36 chassis contains several known stress points that can fatigue or crack under increased grip, power, and suspension load. Subframe mounting points, rear shock towers, trailing arm pockets, and rear sway bar mounts all see repeated stress—especially on cars driven hard on the street or track.

We curated this Rear Chassis Reinforcement Plate Combo to make it easy to address every major rear chassis failure point at once, without piecing together multiple kits or guessing what you might be missing. Instead of buying reinforcements individually, this combo brings everything together as a single, comprehensive solution for the rear of your E36.

The plates are designed to help prevent cracks from forming—or properly reinforce areas that have already seen damage—by spreading load into stronger sections of the chassis. All plates are precision cut from 1/8" steel and are intended to be welded directly into the chassis, becoming part of the structure. Professional installation is recommended.
