The S550 Mustang is a new breed of car, with independent rear suspension (IRS) and the option to get an eco-boost turbo 4 cylinder. We wanted to help these Mustangs put the power to the ground at speed with aerodynamic components that help the chassis out. Front splitter, rear spats, rear diffuser and side skirts are all great additions to any S550 Mustang. We also have hood louvers which help keep the engine bay free of pressure build up. These hood vents are great at keeping the engine and turbo from hot and extreme temperatures created from continuous track racing or high performance driving events (HPDE).
