E46 Rear Subframe/Chassis Reinforcement Kit
Details
Just like the earlier E36 chassis 3 Series, the rear subframe to chassis attachment points on the E46 are all failure prone and can rip away from the uni-body after time. If you drive your BMW E46 hard, chances are at some point you will need to repair this area. We highly suggest doing this modification to any car that is planned for autocross, driving schools, and race use before the damage occurs. Our reinforcement plates are a factory fit and can be installed when subframe bushings are added.
This kit applies to all BMW E46 cars including the M3.
The kit consists 4 main subframe mounting point reinforcements, spacers to re-align the cross member, hardware, and plates to cover the access panels in the trunk.
Welding is required.
Made in the USA
*We also highly suggest replacing your worn rubber subframe bushings with Powerflex polyurethane units. This kit comes in a street(70A) or track(95A) compound to suit your driving environment. This will also help reduce the risk of chassis failure by keeping the subframe secure and not jerking at the chassis mount locations.
