Our Xtreme-Grip coil-overs have been designed for maintain bump travel even with the vehicle lower, both spring rates and valving has been carefully selected for competition.  We have done more testing that just about anyone with the S197 Mustang platform and have put together a variety of packages specifically tailored for everything from daily drivers to purpose built road race cars.

Our base Track system include single adjustable front struts with CorteX-valved Koni internals, and single adjustable rear CorteX-valved Koni eyelet style shocks.

Make sure to review the optional double adjustable front struts and rear damper upgrades, such as JRi, Penske, and Ohlins.

• Our optional custom offset upgrade allows you to run 18 x 10.5 inch wheels and 315mm tires on all 4 corners.

Coilover Benefit: Adjustment

• Lower the vehicle’s centre of gravity
• Adjust the ride height
• Increase the roll stiffness of the vehicle
• Reduce weight transfer in direction change
• Adjust camber and caster angles (if compatible with adjustable top mounts)

This high degree of adjustment is what gives coilovers an advantage over typical MacPherson struts.
