Why Subframe Connectors Benefit Your Mustang - Connecting The Dots

Rear Door-Edge Misalignment Measurement Data

Seat-Mount Flex Measurement Data

A couple coats of self-etching primer helps the topcoat adhere to the welds.

A semigloss black finish matches the rest of the powdercoating.

With the paint dry, we are ready to make our post subframe-connector measurements. We again stress the car in bending and torsion, and duplicate our measurement method. Surprisingly, the changes are minimal and within our margin of error.

Maximum Motorsports' subframe connector kit reinforces this critical area to reduce flex and prevent floorpan damage.

To measure the floorpan stiffness improvement, we again jack up on the right-rear seat-mount bolt until the chassis raises a half inch.

We remeasure the distance between the headrests' points. The reduction in flex is impressive, and explains why subframe connectors make a car feel stiffer.
