BMR Suspension IRS Subframe Support Brace Systems

BMR 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. Features, items, and specs: * 4-piece independent rear suspension (IRS) bracing system * Reduces IRS movement and assembly deflection * Compatible with BMR and other IRS modifications/mounting solutions * Zero decrease in ground clearance * Extremely easy bolt-on installation * Reinforces critical areas of the IRS subframe by reducing leverage * High-quality hardware for installation included

Available in multiple thicknesses and a dozen tubing diameters. How they work: * Weld-In: One flange half is welded to your main chassis structure, and the other half is welded to the removable component (like a crossmember). * Quick-Release: When you need to remove the part, you simply unbolt the two flange halves, allowing for quick maintenance or adjustments without cutting or complex dismantling. * Standardized Sizes: Available for common tubing sizes (like 1 1/4 in. or 1 5/8 in. O.D.) and bolt patterns, ensuring a precise fit for many applications. Key features: * Material: Typically 3/16 in. or 1/4 in. thick steel * Design: 4-bolt square pattern * Purpose: Saves time during construction and makes servicing easier, often used for transmission crossmembers
