Swift - Spec-R Sport Lowering Springs


Swift made Sport Springs Spec-R is made for true track racing enthusiasts that wants to take their vehicle to the next level. These springs are engineered with two main characteristics: 1) Redesigned lowered ride height to maximize the suspension performance, allowing the vehicle to fully absorb road condition for maximum traction. 2) Increased spring rate to further enhance cornering speed through entry & exit. The increase in spring rate is based on the vehicle's factory valve settings. Spec-R Sport Springs are increased to the optimal rate that the stock shocks can handle. Higher performance shocks are not required, but recommended for additional performance gains.

H5S.TW - Motorsport's Most Advanced Spring Material
Swift made a name for itself on the tracks of Asia, Europe, and the USA by defying all accepted concepts and speculations about the future, if any, in coil spring science. When many other companies were looking at expensive and brittle titanium composites to create the next evolution of springs, Swift was looking at reinventing the entire science of coil spring dynamics. Swift saw that most others were using the old regular silicone chrome material, which was not strong enough. They used a heat tempering method that damaged the strength of the material requiring more coils, and in turn, more weight. The material was also suffering from a short life span. With springs like this leading the industry, Swift saw room for improvement.

Swift's R&D team created a material called H5S.TW, which is stronger than the regular silicone chrome material. Because of this material Swift could make the spring wire thinner and could wind the springs with fewer coils, which greatly decreased weight while dramatically increasing the available stroke.

- Aggressive ride stance with moderate drop
- Superb ride quality and performance
- H5S.TW construction for added strength and lighter weight
