AAF E46 Rear Sub Frame Reinforcement Kit
Rear subframe and floor failures are extremely common on the E46 models. Unlike the E36 M3, the E46 models did not receive sheetmetal reinforcements from the factory and subframe and floor failures continued to be a problem well into the E46 production. BMW even has an official fix for non-damaged cars. We recommend EVERY E46 on the road gets rear reinforcement, even if its “just” a street car!
While You’re In There…
Installation requires the removal of the exhaust, rear suspension, subframe, and differential. It is also recommended, but not required, to remove the gas tank. Access to the top of the floor in the rear trunk is also required. With the subframe out of the car there are quite a few additional items that can or should be replaced. Contact us for a special package price on all of the “while you’re in there” parts:
