1987 to 1993 The Road & Track Box Maximum Motorsports

The MM Road & Track Grip Box takes the stock Mustang suspension design to the next level. This combination of parts provides great performance while retaining ride quality suitable for daily driving. Excellent for canyon carving, autocrossing, track days, and daily commuting.

The Road & Track Box takes handling performance as far as the stock suspension design can go while still retaining good ride quality. It provides all the basics: chassis stiffening, higher-rate springs with matching dampers, caster camber plates, improved rear control arms, a Panhard bar, and much more. The difference in performance from a stock suspension is amazing. See the Benefits tab.

What if I want more handling performance? MM has added optional upgrades to the original Road & Track Box that debuted in 1998. These upgrades draw from our top-level Maximum Grip Box and take the performance of the Road & Track Box even higher.
