UMI Performance 4th Gen F-Body Tubular Subframe Connectors are designed for auto-cross, road race and drag race applications and the only 2-point tubular bolt-in subframe connector that ties the front & rear subframes together. This allows better weight transfer for improved traction, straighter launches & increased handling ability while reducing squeaks, rattles and quarter panel flexing. This setup is not visible from the side of the vehicle and does not cause ground clearance issues.
