Maximum Motorsports Mustang Subframe Connectors

Improve your Mustang's performance by increasing chassis stiffness with Maximum Motorsports subframe connectors! These steel tube reinforcements weld to the bottom of the car, and connect the front and rear subframes. This strengthens the flexible floorpan and greatly increases the rigidity of the Mustang's unibody chassis.

MM subframe connectors help put more power to the ground by reducing chassis flex. When stepping on the gas pedal, engine torque will be instantly transmitted to the rear end, rather than lost through flexing of the unibody. This is especially noticeable during drag race launches.

Don't let claims of easy installation lure you into buying bolt-on subframe connectors. There is simply not enough structure in the Mustang's unibody to allow the bolts to be tightened properly. The ideal way to distribute loads across the unibody and prevent chassis flex is to weld subframe connectors to the bottom of the car's front and rear subframes, connecting them together.

Maximum Motorsports subframe connectors include seat braces that attach to two of the four front seat mounting bolts. This prevents the chronic tearing of the Mustang's sheet metal floorpan at the rearward seat mounts.
