Motorsports. Installing the MM Torque-arm will greatly improve your four-link suspension by converting it to a three-link design. Your car will have vastly improved traction, both in a straight line and when exiting corners. Your car will be much more stable and predictable, and you can get on the throttle sooner and harder while accelerating out of a corner. In the stock four-link design, the rear upper control arms are trying to do two jobs at once. One is to control axle wind-up, the other is to locate the axle side to side. When pushed to the performance limit, the upper control arms don't do either job very well. Our Torque-arm suspension system separates the functions of the suspension components-each component has only one job, and is designed to perform that one function with no compromises. The MM Torque-arm controls axle rotation much better than the upper control arms. In addition, the Panhard Bar has the sole job of locating the axle side to side, which it also does better than the upper control arms. The lower control arms primarily have the job of thrusting the car forward under acceleration. The MM Torque-arm suspension system allows complete removal of the rear upper control arms and the quad shocks. The resulting three-link design will articulate freely, even during extreme cornering, acceleration and braking. The free-moving three-link design has so much more traction that the grip at the front of the car will now be the limiting factor (understeer). You should now raise the rear spring rate to increase the rear roll resistance, which takes some cornering load off the front. To meet your needs, Maximum Motorsports has determined the rear spring to match your front spring rate (see Spring Rate Table). These selected rear springs will give you better handling and improved ride quality with your MM Torque-arm suspension system. When we sat down to design our Torque-arm, we listened to what our customers wanted. The three issues we heard mentioned time and again were concerns about ground clearance, exhaust clearance, and access to the differential cover. You talked, we listened! Compared to other Torque-arms, Maximum Motorsports' has over one inch greater ground clearance, nearly one inch more exhaust clearance, and allows complete access to the differential cover. Please specify whether you have round or rectangular subframe connectors.

I really want to stiffen up the rear for harder launches and quicker off the line acceleration with 4:10s in the future.I will be running mostly street tires.

Anyone with experiance with this unit??

It's not applicable to the S197 platform. It is an upgrade to the Fox/SN95, which uses a completely different OE rear suspension arrangement.

The advertising copy quoted above is not technically correct, even though the number of longitudinal components is three and that it also has to use a PHB (or Watts link). A torque arm is not the third link in a 3-link because it works somewhat differently.

Edit: You're most likely looking for anti-squat brackets (aka "LCA relocating brackets"), LCAs with harder bushings or rod ends, and maybe a different UCA and bracketry.

Hi stealth_GT,

This partis for SN95 or Foxnot S197 chassis cars based on the description. You can buy a Torque arm from Griggs Racing for the S197 chassisbut IMO the 3-link is a better setup handling wise.In terms of IC (Instant Center) a well configured and setup3-link can give you the best of both worlds with the IC moving rearward under accelleration for better gripand forward on decelleration for better stability under braking. With a torque armthe IC isfixed and does not move and cannot be adjusted easily. Torque arms are also heavywhich hurts ride and grip on uneven pavement.

Steeda makes the best UCA/UCA mount system with the longest UCA available and the only LCA designed to take advantage of better geometry from a longer UCA and repositioned UCA mounting bracket. Combine the Steda Competition UCA/UCA mount and a pair of street adjustableSteeda LCA's and you have a pretty good rear end set up, all you have to do is add a Watt's link and coilovers and...

HTH!
