All suspension loads go through the front and rear subframes and into the central unibody structure. The Mustang unibody bends and flexes because the front and rear subframes of the car are connected by the unsupported and flexible center portion of the floor pan.

Maximum Motorsports' subframe connectors are welded to the bottom of the unibody, connecting the front and rear subframes and supplying more structure than is provided by the floor pan. This increased structure reduces the amount of bending and twisting in the chassis.
