Tanabe Sustec Pro: Race-Proven Coilover Spring and Shock Assemblies

When it comes to coilover spring and shock assemblies, few names carry the pedigree of Tanabe. Since 1982, Tanabe has earned recognition as a trusted manufacturer of quality automotive parts for performance applications, growing from its roots in Osaka, Japan into an internationally renowned brand. That engineering heritage flows directly into their Coilover Spring and Shock Assembly lineup — a product category where Tanabe's motorsports DNA is most clearly on display.

The Sustec Pro Series: Engineering Comfort and Performance Together

The Tanabe Sustec Pro Series adjustable coilover suspensions offer a fine range of performance and comfort for the motoring enthusiast, with internal valving tuned for a wide variety of driving needs — allowing high performance and comfort to genuinely coexist. This philosophy sets Tanabe apart: rather than forcing drivers to choose between a punishing track setup and a wallowing street ride, the Sustec Pro line is built to deliver both.

Within the Sustec Pro family, several distinct models address different performance targets. The Sustec Pro S-0C is built for those who desire both high performance and maximum comfort, dispelling the popular belief that a firm or harsh ride is a sign of a performance suspension — its short stroke, shortened case dampener delivers superior handling without sacrificing strength or ride comfort. A unique double-cylinder design allows for full suspension stroke within the shortened shock body, while low-pressure gas ensures smooth rebound characteristics for additional ride comfort.

The Sustec Pro CR variant takes a model-specific approach. It employs a non-preload valve technology that greatly reduces unpleasant bumpiness — the leaf valve of the damper piston is a non-preload valve that does not require preload to bring the valve seats into close contact with each other. This design allows for millimeter-precise ride height adjustment via screw-type adjustment, with a wide range of height settings available while maintaining improved ride quality. Each component is finished with corrosion-resistant coatings to protect against rust and wear, ensuring long-lasting performance even in harsh driving environments.

At the top of the range, the Sustec Pro SEVEN is an all-new adjustable coilover suspension featuring circuit-developed technology, with the key difference lying in its highly unique internal construction and slide valve technology — allowing a great range of adjustability and function from both sides of the performance spectrum.

Built to Last: Manufacturing Quality

Everything is produced in-house under strict quality control at the Tanabe factory in Shiga, Japan, with manufacturing and production methods certified to both ISO9001 and JISQ9001 standards. Durability is validated to "1/100 mm" tolerance standards for seal and rod parts, with the oil seal durability test requiring a stroke of one million times and endurance equivalent to 100,000 km of driving.

Street, Track, or Daily Driver

Tanabe's extensive racing experience allows its engineers to apply motorsports technology to everyday automotive use, creating premium parts that feature high durability, increased safety, and maximum performance. Whether you're building a dedicated track machine or simply want sharper handling and a cleaner stance on your daily driver, Tanabe's coilover spring and shock assemblies are engineered to elevate the driving experience without compromise.
