BMR Boxed Subframe Connectors for outside frame-rail exhaust, 1982-92 F-body Hardtop.

The Third Generation of GM’s F-body needs all the help it can get with chassis reinforcement. Commonly known as one of the most flexible and "loosest" chassis’ ever produced (by GM) we made sure that our sub-frame connectors were up to the task. As with most of our sub-frame connectors, we reinforce the rear control arm mounts with HD 3/16" laser cut plate and use rectangular tubing to join three areas: the rocker pinch welds, rear control arm boxes and front sub-frames. This ties in the entire floor-pan of the car by joining key structural components, minimizing chassis flex and improving handling.

BMR offers two versions for different exhaust combinations. Part Number SFC008 is designed for cars with full length headers and exhaust systems that run inside the frame rails. Part Number SFC009 is designed for cars equipped with the OE manifolds or shorty headers with OE exhaust or OE type exhaust that runs on the passenger side, outboard the sub-frame.
