Steeda S550 Ford Mustang Rear IRS Subframe Support Braces
Reinforce your late-model Ford chassis with Steeda S550 Mustang rear IRS subframe support braces. These chromoly steel aftermarket stabilizers connect three key points on either side of the undercarriage: the rocker panel, the front mount of the rear suspension subframe, and the rear mount of the lower control arm. This adds much-needed rigidity and overall control of the vehicle. Steeda braces will limit twisting and vibrations for improved cornering, less wheel hop, and no additional noise. The stiffeners use existing holes in the chassis, and require no modifications—installation takes about an hour with regular shop tools. Leave the factory bracket in place; these subframe braces offer twice the support. Enjoy better handling and a safer ride with a pair of Steeda S550 Ford Mustang rear IRS subframe support braces.
