Description

The Steeda Rear IRS Subframe Support Braces (part number 555-5754) are engineered for 2015+ Ford Mustang Fastback Coupes with the S550 or S650 chassis. These braces connect the rocker panel, the front of the IRS subframe, and the rear lower control arm/toe link mounts. Constructed from 4130 chrome moly steel and finished with a silver metal flake powder coat, they significantly reduce IRS deflection for enhanced stability and control.
