Metric Coilover Springs
Less unsprung mass, more stroke, increased handling. The only thing you will be loosing is track time.


Swift's flagship products that made Swift a regular name in the worlds most famous racing series. These products have been the child for over 80 years of industrial spring experience. Hundreds of engineers proven concepts and theories were materialized in this springs development. The end, the product is the lightest, most durable, and the most linear spring rate on the market.

While most track racers have already began the ritual of swapping their springs, many swap from one brand to another let you notice the stiffness only as being either softer or harder. What if a spring could change other dynamics, such as a noticeably lighter unsprung mass, smoother weight transferring, better ride quality, lower tire temperature, and increased ability to anticipate vehicle reaction? Like most racers, Swift team hates to hear “what if”, so they built the “what if” into reality.

H5S.TW
All of the Swift Springs are made with our exclusive material called H5S.TW.

Motorsport's most advanced spring material

Swift made a name for itself on the tracks of Asia, Europe, and U.S. by defying all accepted concepts and speculations about the future, if any, in coil spring science.

When many other company 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 are using the old regular silicone chrome material, which was not strong enough. It used a heat tempering method that damaged the strength of the material that requiring more coils, in turn, more weight. The material was also suffering from a short life span. With springs like this leading the industries, Swift saw room for improvement.

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

Our metric coilover springs are measured and rated in the metric system. The metric system is used widely in the sports compact market, and therefore we want to provide an easy understanding for the suspension tuners.
We offer the widest range of metric coilover springs from 3kg through 34kg in various inner diameter and springs length.
The diameter, length, and rates that we offer will cover users with a need of a daily comfortable commute, up to world class racing machines. Which ever suites the needs of the individual!
