GR-40/GR-350 Suspension Systems | Individual GR-40 Upgrades | Complete Parts List

Your Mustang now stops, launches and corners predictably. The next step is to fix the front end to make the car responsive and to improve high-speed stability and weight distribution.

By installing our GR-40 K-Member and Coil Over system, the car can be lowered even further without hurting the geometry. The SN-95 spindles we installed previously have added over an inch of suspension travel. The K-Member radically reduces scrub-radius and corrects Ackerman, so steering response is much improved. Caster is nearly doubled for better straight-line stability, control arm locations are changed to reduce body roll and to eliminate the remaining components of brake-dive.

Prices for the Tubular GR-40 front end pieces which together eliminate about 50 lbs. of weight from the front of your Mustang, start around $1,189.00. The GR-40 kit installation is now complete, and the humble Fox-chassis car will now out-corner and out-stop a ZR-1 or a Viper, and support massive horsepower additions with perfect balance.
