Description
XR1 is our main flagship line of coilovers. Featuring an industry leading oversized casing with inverted monotube technology standard, XR1 dampers have a higher oil capacity and larger piston diameter resulting in access to a wide range of adjustment for ultimate response without compromise. Drivers of all levels can easily adjust the damping for a sport-tuned yet comfortable ride on the street and are able to quickly dial in a more aggressive setting for characteristics needed at the track.
Utilizing the very same technology found in top tier racing, Stance Suspension development of the XR1 coilover answers the demand for a true high performance suspension able to conquer the challenging dynamics of the street. The days of sacrificing ride quality for performance are over!
