Coil-Overs Uniquely for Street Use

Coil-over shocks and struts have gotten a bad reputation in the mustang market as being too harsh for street use and best suited for track-only cars.  We are not surprised since the majority of aftermarket coil-overs a poorly engineered with the insufficient suspension travel causing bottoming, incorrect spring rates, and valving not suitable for the intended use.

Not so with CorteX Xtreme-Grip shocks and struts. The Xtreme-Grip street coil-overs have been designed for maintain bump travel even with the vehicle lower, both spring rates and valving has been carefully selected for the best driving experience.  We have done more testing that just about anyone with the S197 Mustang platform and put together a variety of packages specifically tailored for everything from daily drivers to purpose built road race cars.
