BMR Fabrication 2005-2010 Mustang - Tubular Subframe Connectors Tubular subframe connectors are made from 1.75" diameter DOM tubing and 3/16" laser cut mounting plates. The design can be welded without the need to remove interior carpet. The design reinforce the rear control arm mount. The design will retain OE ground clearance. Ford's new Mustang platform is a vast improvement over the Fox body with chassis rigidity upgraded over 30%. While this is good news, it is still a uni-body and we are still left with a front and rear subframe that is not connected. BMR subframe connectors take over where the factory left off. Both tubular and boxed designs complete the frame by tying the rear control arm mounts and subframe assembly to the front subframe. The HD boxed subframes go a few steps further by triangulating key structural points together to make a very rigid frame. Available in Black Hammertone or red powdercoat. NOTE: Fits v8 and v6 models. Will also fit convertibles if rear bracing is removed.
