Designed on the principle that a sports car doesn’t have to ride harsh or uncomfortably to still perform when pushed to its limits. That means whether you are getting to the track, chasing times on course or picking up your date after, FastRoad Pro™ coilovers will all ways keep you composed.

Each application we offer is individually tailored to its chassis. During on chassis testing we monitor multiple conditions with our data acquisition systems to confirm the suspension and vehicle dynamics. Valving is then verified with our in-house Roehrig® dynoes.  Springs rates are carefully chosen to provide a balance between blistering performance and remarkable comfort. We don't believe in settling for off the shelf valving, and neither should you.

Engineered in-house in California, FastRoad Pro™ coilovers are hand-assembled using a network of quality suppliers located in North America, Europe, and Asia. Each shock is verified for performance on a shock dyno before being sent out. FastRoad Pro™ is a one and done suspension solution for the discerning sports car enthusiast that is made to last.
