More road racing national championships around the world than any other Miata coilover

The Gen2 Xida are built for us by Tractive Suspension (Netherlands) using Hyperco (USA) springs. The exceptional valving sensitivity produces both incredible grip over any paved surface and exceptional ride quality. Despite the surprising streetability, these are purpose built racing dampers intended for use under the most demanding motorsports environments. NASA PT/TT 5 points
