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. BMR's design completes the frame by tying the rear control arm mounts and subframe assembly to the front subframe as well as triangulating key structural points together to make a very rigid frame. Features Boxed subframe connectors are made from heavy duty 1.5"x 2" main tubing and use both 1"x 2" and 1" gussets as well as 3/16" laser cut weld plates. Can be welded without the need to remove interior carpet. Also reinforces the rear control arm mount. Design retains OE ground clearance. Note: Fits V8 and V6 models. Will also fit convertibles if rear bracing is removed. Application: 2005-2008 Mustangs
