Unit 14 Performance E46 Rear Chassis Reinforcement Kit
Our Unit 14 Performance E46 Rear Chassis Reinforcement Kit is designed to strengthen the rear section of the chassis by reinforcing the subframe mounting points and RTAB pockets. Manufactured from 2.5mm mild steel, this kit helps prevent cracking and failure in these well-known weak areas.
