GR-40 Suspension Kit Pricing
Autocross/Open Track
Autocross cars are unique challenges because they must have terrific grip, yet be nimble enough to negotiate extremely tight low speed turns. The GR-40 Autocross package may actually have too much rear end grip (yes it's possible in a Mustang) for some Autocross courses. The GR-40 Autocross package adds a greater level of weight reduction, complete adjustability and looser balance to get around tight corners. If you only plan on occasional competition consider adding just the rear upgrades. If you are serious about winning, you will need a Torque-bias differential to complement the chassis.
