This Steeda Independent Rear Suspension (IRS) Subframe Brace is designed for a 15-17 Mustang GT, GT350, EcoBoost 2.3, and V6 3.7 (Fastbacks Only). These braces are designed to limit the movement of the subframe and help reduce wheel hop. They utilize existing threaded holes in the rocker panel to connect to the front mount of the IRS to the rear mount lower control arm and toe link to improve rear end rigidity and stability. Each brace is constructed from 4130 chrome-molly steel and powder-coated silver metal flake for great looks and durability.
