The SN95 Mustang ratio is different from the Fox chassis ratio because of differences in the unibody chassis. The MMBAK-10 kit for 1979-93 Mustangs has a ratio of 6.15:1. The MMBAK-13 kit for 1994-95 Mustangs has a ratio of 5.32:1. These are the ratios when the MM pedal pad is in the stock position on the pedal arm. The ratio can be increased or decreased slightly by changing the pedal's position on the arm.

It will increase straight-line traction. It will provide more rear grip during cornering. It will improve corner-exit acceleration. It will provide superb control and predictability. It will increase wet weather traction. It will improve ride quality.

We determined the limits of each torque-arm by destructively testing them. Each torque-arm was then rated for the most difficult scenario possible: a high-revving-sidestep-and-dump-the-clutch launch, with no clutch slippage, on sticky drag tires that grip the pavement instead of burning rubber. That's the type of launch that will send the front tires skyward. If you don't mount up sticky drag tires and drive your Mustang like that, then the maximum rear wheel torque ratings listed may be disregarded for your situation.

Yes, the upper control arms must be removed. The torque-arm is not an add-on traction device. It is a fundamental change in the rear suspension design. A torque-arm suspension is a variation of a 3-link suspension. Plus a panhard bar. Leaving the upper control arms in place would cause massive suspension binding because you would have both a 4-link and a 3-link suspension on the same car, with both systems trying to cause their own particular rear suspension motion.

There are two good methods of controlling the side-to-side location of a rear axle, a panhard bar or a Watts Link. MM's Engineering Team chose the panhard bar because it allows a much lower roll center than a typical Watts Link design. A lower roll center reduces the tendency for the inside rear tire to lift and unload during cornering. As a welcome bonus, a panhard bar is far less complex, less expensive, lighter, and allows for the use of tail pipes!
