This BMR Lower Torque Box Reinforcement Plate kit for 1979–2004 Fox-chassis Mustangs includes plates and hardware to reinforce the lower rear control arm mounts. CNC-formed from steel, the components bolt into existing mounting points to add strength to a known weak spot in the chassis. The kit is intended to reduce the risk of torque-box damage that can cause alignment and handling issues.
