Reduce chassis flex and increase the handling capabilities of your Mustang with tubular, weld-on subframe connectors from BMR Suspension. The 1979-2004 Mustang chassis flexes dramatically, even with mild amounts of torque and horsepower. BMR’s subframe connectors are manufactured from heavy-duty 1 5/8-inch steel tubing with laser-cut CNC-formed 3/16-inch steel plates. This adds loads of strength in all the right places. These weld-on subframe connectors are engineered to considerably strengthen the chassis and reinforce the rear suspension.
