Set of Maximum Motorsports Full Length Subframe Connectors for all 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003 and 2004 Mustangs.

If you own a 1979-2004 Mustang then you need to consider strengthening the unibody with a set of Maximum Motorsports Full Length Subframe Connectors from CJ Pony Parts!

The Maximum Motorsports (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 Motorsports Full Length Subframe Connectors?
- MM full length 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 full length subframe connectors do not hang any lower than the lowest part of the car, which is 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 Subframe 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.

Rated 5 out of 5 by from Track Must Have!! This is a great product, improves the stability of the vehicle around the track on high speed corners, allows you to feel how the car is handling based on the seat to sub-frame connection. As for the instillation, drivers side is a breeze but passenger side is a pain due to the fuel and brake lines being in the way. The lines are very hard to get out of the way since they are hard lines, welding in this area is nearly impossible. Great product, recommended for any mustang, really stiffens up the entire vehicle.

Rated 5 out of 5 by from Makes the chassis the way it should be. They shipped very fast and crossed the country in a week to my door which was great. Quality is great and you can tell they were well engineered. All te welds on it are perfect as well. Install wet fairly smoothly. The only setbacks being the fuel lines on the passenger outer side and the exhaust had to be moved slightly to allow room for the mig gun. They fit quite well with only slight amounts of pushing and pulling. On the car every bump is so much more solid and you can feel it twisting much less through the seat brackets.

Rated 5 out of 5 by from no surprises I just bought and installed these MM full length subframe connectors on my '85 GT. There were no surprises, they fit nicely, the instructions were easy to understand and shipping was reasonably fast. They were packaged well and arrived with no damage. I'm very happy with the connectors.

Rated 4 out of 5 by from A lot stronger than the bolt on ones. This kit is a great kit. The directions with this kit are excellent. Gives step by step directions to the tee. Everything came in the kit to do the installation. When rails were welded in I went for a test drive and you can definitely tell your mustang is a lot more stable in the cornering department.

Rated 5 out of 5 by from Great Sub Frame Connectors Even though I had a rough time installing these on my car ( it was raced for years without sub frame connectors), these are high quality connectors. All hardware is included and correct. I would definitely recommend these to anyone that is looking to purchase sub frame connectors.

I have a 2001 Cobra SVT Mustang Convertible. Its converted to right hand drive when first imported to Australia. Should this male any difference? For street use will this improve as well? Or is it for track only?

Asked by: Giffo
This part will improve the ride and handling of your Mustang everywhere - the road and track! I'd recommend reviewing the installation instructions (linked on the product page) to see if the changes you made when you converted to right hand drive would affect the installation. My guess is that you're going to be fine, but I can't say for sure without knowing anything specific about your Mustang.

Maximum Motorsports says they're universal across the 1979-2004 Mustang model line, so you should be good.
