The NF210 coil spring features a tasteful drop, and produces the best overall ride quality and comfort for a performance lowering spring. The lowered stance of the NF210 gives the car an elegant pose, while the spring rates, which are only slightly raised (up to 5% over stock) retain factory ride quality settings.
This coil spring is extremely popular with luxury tuned vehicles, as well as those with larger diameter wheels that want to eliminate fender gap, but maintain excellent driveability while reducing the risk of damage to wheels that is associated with stiffer suspensions.
For those who demand the best comfort from a lowering spring
Sustec 210 Technology: NF210 Lowering 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!
