The Tanabe Sustec Pro S-0C coilover system has been designed is for performance enthusiasts who need both high performance and maximum comfort from a fixed damper suspension system. Dispelling a popular belief that extreme levels of noise, vibration and harshness are characteristic of a 'true' performance suspension, the Pro S-0C system is extremely unique in that the internal construction allows for superior handling without sacrificing strength or ride comfort. The difference is in the short stroke and shortened case damper that make this supposedly impossible request a reality. In addition, the unique double-cylinder design of the Pro S-0C allows for full suspension stroke within the shortened shock body while low-pressure gasses ensure smooth a rebound for additional ride comfort. All Pro S-0C coilovers include helper springs to keep main coil seated, assist with rebound stability and adjust preload for maximum comfort and suspension travel. The forged aluminum spring seats and lock nuts are coated to resist rust, prevent corrosion, ensure durability, and provide many years of comfortable performance driving both on and off the track. Tanabe Sustec Pro S-0C coilovers feature height adjustability but (non-adjustable) static valved dampers.
