Race Springs are made with extremely high tensile strength wire alloy which allows the use of a thinner wire. Manufactured using advanced materials and precision technology in Germany, H\u0026amp;R 2.50  I.D. Race Springs are crafted from special lightweight (hf) 54SiCr6 spring steel. For any given spring rate, they are on average 15% lighter and have 10% more travel than competitors  springs. Main springs range from 6  to 18  in length and are available in a wide selection of spring rates.  TENDER SPRINGS: H\u0026amp;R 2.50  I.D. Tender Springs are made of trapezoidal (flat rather than round) spring wire and have a low block height for maximum travel. These springs are designed for demanding motorsport environments, and like all H\u0026amp;R springs, have been pre-blocked at the factory so they will never set or sag. The H\u0026amp;R 60mm I.D. Race Spring line is crafted from special lightweight (hf) 54SiCr6 spring steel and is the most comprehensive 60mm I.D. Race Program in the U.S. If you own a Porsche GT3 or another Euro spec car, our range of 60mm I.D. Race Springs has you covered. With hundreds of main springs and tender springs available, H\u0026amp;R has the lengths and rates necessary for optimal tuning and setup.
