PRO210 is a fixed diameter, linear high performance coil spring for use on adjustable coilover suspensions. PRO210 is used on all Tanabe Sustec Pro suspensions, and the technology developed for PRO210 is used in ALL Tanabe performance coil springs.
The PRO210 spring was developed through rigorous R&D spanning many years and tested on JGTC and N1 endurance cars on Japan's fastest circuits. Due to the constant stresses involved in N1 endurace racing, our involvement was necessary to produce a spring of extreme quality, lightweight, extreme durability, and exact specifications to meet the needs of circuit racing.
Various materials were tested, and it was found that SWI200 steel alloy would prove to be the most durable if manufactured properly. Materials such as titanium were tested, but titanium had exhibited shortened durability and was also very expensive. Through a highly advanced manufacturing process, an amazing tensile strength of 2100nm was acheived using only SWI200 steel alloy. No other manufacturer has been able to reach this level of strength in a coil spring-- even those that use more expensive materials to strengthen their coil spring.

All of our coil springs feature SUSTEC 210 Technology. Sustec 210 Technology is a series of manufacturing methods developed to create a stronger, thinner, and lighter spring using only high tensile steel, without adding additional elements that could affect quality, durability, or price. "210" stands for 2100n/m of tensile strength, which is the highest strength ever acheived in a coil spring. The Tanabe Shiga factory in Japan is home to some of the most advanced, unique coil spring machines and processes in the world!

The coil spring on a suspension dictates suspension travel, and most importantly, how it travels. Due to this, the coil spring quality and uniformity of spring rate and length becomes extremely important. Sustec 210 technology ensures exact spring rates between left and right sides, as well as equal spring lengths that will not sag. Click here to read more about upgrading the springs on your coilover to the PRO210.
The PRO210 spring may be used on any Sustec Pro suspension, as well as other manufacturer's dampeners for special tuning of the spring rate. Custom spring rate sets are perfect for custom vehicle applications, or performance needs. Click here to rear more about special suspension tuning with spring rate.
