The H&R 2.50" I.D. race spring is a single 12-inch coil rated at 300 lbs/in, built for dedicated suspension tuning and motorsport use. Produced in Germany from lightweight (hf) 54SiCr6 spring steel, the high-strength wire allows thinner coils for reduced mass and added travel. H&R reports these springs average about 15% lighter and provide roughly 10% more travel than comparable springs; the program offers many lengths and rates and springs are pre-blocked at the factory.
