E46 M3 x Subframe Reinforcement

Jul 16, 2010

Recently we installed a Subframe reinforcement kit on a customers E46 M3. This is not an easy task, but a necessary one. A common problem with the E46 M3's is the rear floor where the subframe mounts. Under constant torque from acceleration and deceleration, the floor can crack around the mounting points for the rear subframe. If you are unsure if your M3 is suffering from the same problem, give us a call and get it checked out. It's easier (and cheaper) to remedy this issue before the floor starts to crack.
