MM's Road & Track springs improve handling while maintaining good ride quality. The spring rates were carefully chosen to provide a good balance of handling and ride quality. Expect reduced understeer, improved steering response, reduced body roll, and reduced brake dive. Good level ride characteristics are maintained for reduced pitching on larger bumps, and short bumpstops are included, making this kit suitable for the enthusiast who drives their Mustang daily.

These springs are at the heart of the MM Road & Track Grip Box for the S197 Mustang chassis. Testing showed the Road and Track Box pushed cornering power to above the 1.2g level while retaining ride quality suitable for a daily-driven Mustang.

Lowering

Front: 1.8"
Rear: 1.9"
Lowering amounts are approximate, and will vary with year and model due to differences in car weight.

Spring Rates

Front: 320-360 lb/in. The rate is progressive and approximate, ramping up from 320 lb/in at ride height to 360 lb/in at 2" of spring compression (about 1.9" of wheel travel).
Rear: 260-380 lb/in. The rate is progressive and approximate, ramping up from 260 lb/in at ride height to approximately 380 lb/in at 2" spring compression (wheel travel is also 2" because the rear spring is on the axle).
