H&R Race Springs 2.50" I.D. Lightweight 54SiCr6 Steel

H&R Race Springs 2.50" I.D. Lightweight 54SiCr6 Steel Precision German engineering delivers race-proven suspension performance. H&R 2.50" I.D. Race Springs are made from high-tensile, lightweight 54SiCr6 spring steel, allowing thinner wire construction for reduced weight without sacrificing strength. Lightweight construction — typically ~15% lighter than competitors for improved unsprung mass and responsiveness. Increased travel — about 10% more travel for better compliance and control on track. Wide range — main springs available in multiple lengths (6"–18") and a broad selection of spring rates for precise tuning. Tender spring option — trapezoidal wire tender springs with low block height maximize travel and are optimized for demanding motorsport use. No set or sag — factory pre-blocked to maintain consistent performance over time. Ideal for track and high-performance street applications, including European models like Porsche GT3. H&R's comprehensive 60mm I.D. program further expands tuning options with hundreds of main and tender springs covering long lengths and a wide range of rates. Benefits: reduced weight, more travel, precise setup, proven durability — engineered in Germany for serious motorsport tuning.
