About this product

Part #: TBR004H

Increase stiffness and reinforce the torque boxed in your 1979-2004 Mustang with Torque Box Reinforcement Braces from BMR Suspension. The Fox-chassis Mustangs we not known for being super strong. When large amounts of torque are applied to the Fox chassis, the factory torque boxes are known to crack and rip. This causes all kinds of rearend alignment issues, poor performance, and unsafe driving conditions. Designed from CNC-laser cut, CNC-formed steel plate and DOM steel tubing, BMR?s Torque Box Reinforcement Braces are designed to bolt into the ?79-?04 Mustang chassis, adding strength to the upper and lower control arm mounts. This means you can put as much power and torque to the wheels as possible, without fear of damaging this critical area of the chassis.

Bang for buck handling mod. Does add a little more bounce to the car, but overall it handles much better than stock.
Any additional comments?
The car looks great with the lowered stance, but I would suggest going with lower springs, as there is still a bit of a gap.

Was it easy to install? Any installation tips that will help others?
This part was tricky to install. The control arms had a sharp edge that cut into the bushing when pressed in. I used a die grinder to cut a chamfer in the control arm and a lot of silicone grease.

Finished parts are then assembled and packaged in the assembly department. By manufacturing every product in house, BMR can control the quality at every stage of the manufacturing process.
