The HT dampers are an outcome of TEIN's extensive experience in tarmac racing combined with the latest cutting edge technology in suspension tuning. These dampers have been developed for drivers serious about performance and those seeking quick and sharp response on all surface conditions. They are the perfect choice for circuit use and competitions such as Auto-X and Gymkhana and will give you a definite edge over the competition in terms of grip and handling. The spring rates and damping force have been chosen for the best possible grip on tight courses and the separate compression and rebound adjustment enable you to fine tune the settings to match different road conditions and circuit layouts.
