The FIT System is a modular approach to achieving the ultimate in chassis stiffness and strength through design.

By integrating three key components into a modular system, the Fully Integrated Technology (FIT) System has taken the next step beyond normal stiffening products. Not just randomly conceived and grouped together parts, countless hours of research and testing have gone into fully optimizing these systems!

End result..... the ultimate in chassis stiffening for your Mustang!
This FIT System includes:
Subframe Connectors .......P/N: SFC-M01
Stiffening Rails ...................P/N: SR-M01
Web Brace ..........................P/N: WEB-M01
