The H&R 2.50" I.D. race spring is a single 12-inch coil rated at 150 lbs/in, built for precise motorsport suspension tuning and custom setups. Made in Germany from lightweight (hf) 54SiCr6 spring steel, the high-tensile wire allows thinner coils for lower mass. Compared with typical rivals these springs are about 15% lighter with roughly 10% more travel; main lengths and rates are offered across a broad range and springs arrive pre-blocked.
