Developed from actual competition TEIN was able to create a fully adjustable damper that can be easily tuned for any track and weather conditions. Super Racing Dampers utilize a full-length adjustment system to allow shock length and spring pre-load to be adjusted independently. Separate 16 - way adjustments for compression and rebound damping enable the user to fine tune for any situation. TEIN has incorporated both camber and caster adjustment into the front pillow ball upper mounts for strut type vehicles. External reservoirs on SA type dampers allow for added oil capacity. Spring rates and shock valving were derived for many years of motorsports support, to provide the ultimate damper for competition. Designed and tested for circuit use by advanced and professional drivers who are seeking complete damper tuning capability.
