Our E46 rear subframe reinforcement plates are designed for the back half of the E46 (M3 as well as Non-M). They will help prevent cracks and/or repair cracked subframe mounting points on the chassis and rear shock towers. This is the optimal solution for protecting your E46 from heavy street or track use. Our subframe reinforcement plates are precision cut from 14 gauge cold rolled steel. Our rear shock reinforcements are cut from .125" steel. Installation requires welding.
