The GF210 coil spring is geared towards maximum performance, without compromising daily driveability. A subtle drop provides an aggressive stance, while the higher spring rates (+20% - 30% over stock) provide excellent handling and vehicle stability characteristics. These springs provide a very noticeable gain in performance when installed.
The GF210 is well-mated with a performance shock upgrade to extract the full potential of the coil spring, but will also work with factory equipment.
Each coil spring application is tested for fitment and optimal weight distribution for sportier handling.
Sustec 210 Technology: GF210 Performance 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 achieved 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!
