Recent rule changes allow these to be used in certain classes of racing. These springs offer the advantage of a lightened retainer, multi-arc (egg-shaped) wire, variable rate, and ultra high frequency. Combine these design features with the latest in heat treating and alloy selection and you have a significant performance advantage over traditional springs.
