H&R Race Springs 2.5" I.D. Lightweight 54SiCr6 Steel Engineered in Germany for motorsport use, H&R 2.50" I.D. Race Springs are manufactured from lightweight 54SiCr6 high-tensile spring steel. Advanced materials and precision production allow thinner wire with superior strength, reducing weight while increasing travel. Lightweight design: Approximately 15% lighter than comparable springs for reduced unsprung mass. Increased travel: About 10% more travel than competitors at equivalent spring rates. Wide range: Main springs available from 6" to 18" and a broad selection of spring rates to suit tuning needs. Tender springs: Trapezoidal (flat) wire construction with low block height for maximum travel and consistent performance. Pre-blocked: Factory pre-blocked to prevent setting or sag under demanding race conditions. H&R also offers an extensive 60mm I.D. Race Spring program for Euro-spec and high-performance vehicles like the Porsche GT3. The 60mm range covers main springs 80mm–300mm in length and spring rates from 25 N to 700 N, providing precise options for corner balancing and optimal chassis setup. Ideal for: Track-focused builds, professional motorsport teams, and enthusiasts seeking lightweight, high-travel springs for improved handling and ride control.
