Product Description:
Ridetech HQ Series S550/S650 Mustang Rear Coilovers are the latest to hit the market for the popular Blue Oval muscle car. While the car still bears the ‘Mustang’ name, Ford has evolved the persona of the traditional pony car over the S550 & S650 generations to assume a more capable grand tourer role. As such the car has adopted an independent rear suspension layout and enjoys more capable sports-car like handling. That said, there is always room left on the table for improvement with factory muscle, and Ridetech’s adjustable coilover suspension allows for an aggressive yet functional stance and improved handling performance without sacrificing ride quality or comfort.
Ridetech’s latest coilover system is sporting a fresh new look, featuring a black and gray anodized finish that pairs nicely with blue Hyperco springs. Also, HQ Series S550/S650 Mustang Rear Coilovers are 24-position rebound adjustable and feature Fox Factory valving and internals. This allows for fine-tuning of suspension responsiveness, whether the car is put to use on the 1320, on the autocross, or road course use.
