The DF210 coil spring offers a large drop, while retaining superb ride quality characteristics. The spring rate is raised 10-15% to compensate for the shortened amount of suspension travel, without over-stiffening the spring rate and affecting ride quality and shock lifespan.
The DF210 is unique in that it provides an excellent range of benefits, from it's extremely low stance, to performance and comfort. Overall, the DF210 is extremely well balanced for those looking to lower their car, increase handling potential, and maintain comfort.
For those who want the lowest drop.
Sustec 210 Technology: DF210 Lowdown 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!
Lowering: EXCELLENT (Drops of up to 2.5" are available.)
Comfort: VERY GOOD (Spring rate is raised no more than 10-15%)
Performance: GOOD (Lower center of gravity)
