If you own a E46 NM or E46 M3 and you are experiencing unfamiliar sounds coming from the rear of your BMW whenever the throttle is being applied, then chances are that your rear subframe sheet metal may already been torn away and is the cause of these noises.
The whole rear subframe of the BMW as well as the differential and rear suspension are all secured by bolts threaded into the sheet metal body. It is the splitting and cracking away of the sheet metal around the threads that causes this problem. Continuous fatigue can eventually leave nothing in place to hold the rear end of the car securely.
The Active Auotwerke plate kit includes all the necessary reinforced metal plates to properly secure and reinforce your BMW back to it's intended state.
Professional welding and installation is required as well as a re-alignment of the suspension.
This is an essential upgrade whether you have a completely stock or a modified E46.
