BMR SuspensionCB762HChassis BracingBMR Suspension IRS subframe support brace systems are designed for use with late model S550 Mustangs and compatible with stock bushings or BMR's popular cradle lock-out kit. This bracing adds additional rigidity to the independent-rear-suspension-to-chassis mounting, as well as additional reinforcement to the subframe itself. It achieves this by tying in to the front leg of the subframe where leverage is reduced. A super heavy-duty plate locks in beneath your sway bar mounts and gets tied into the rear bushing mount. Reinforce the weak points on your 6th generation Mustang for improved performance with a BMR Suspension IRS subframe support brace system.
