The FIT system integrates the front and rear subframes and ties them into the rocker panels to form a triangulated web of strength and stiffness that helps keep your car in shape for improved handling, launches, and ride quality. The strong steel stiffeners beef up your Mustang for an increased range of suspension tuning and overall performance. Twisting and bending is good conditioning for humans--not vehicles.
