Product Description

Set of Maximum Motorsports Full Length Subframe Connectors for all 1979-2004 Mustangs.

The MM weld-on subframe connectors improve handling and ride quality by reducing chassis flex. This helps to keep the forces caused by road irregularities in the suspension, rather than being absorbed by the flexing of the unibody. This results in a Mustang that will be much more dampened and controlled over rough roads, eliminating the shaking and shuddering that is characteristic of stock Mustangs.

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 floor pan at the rearward seat mounts.

Why use Maximum Motorsport's Full Length Subframe connectors?
MM XL Series subframe connectors are 95% stiffer than standard subframe connectors.
MM subframe connectors are strong enough that you can lift the car by placing a jack anywhere along the length of the connector tube!
Extends from the rear lower control arm attachment point on the rear subframe all the way up to the firewall, providing substantially more weld area than other connectors.
Made of 1.5" x 2" x .083" wall thickness rectangular tubing.
MM XL Series subframe connectors do not hang any lower than the lowest part of the car-the exhaust system.
MM created the first Full-length Subframe Connectors; beware of imitators who attempt to copy the original innovative design.

Why use weld-on connectors?
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.

*1996-1998 Cobras must notch the transmission crossmember at the frame rails so that the subframe connectors can sit flush on the frame rails.

I had CJ Pony Service install these on my Fox Body and I cant believe the difference that they made. You can instantly tell the chassis is much stiffer. Instead of rattling and twisting over bumps it feels like the suspension, not the chassis, is finally absorbing the bumps they it should. This should have been my first modification.
