H&R 2.5in ID Race Springs Lightweight 54SiCr6 Steel High Tensile Alloy

H&R 2.5" I.D. Race Springs — Lightweight 54SiCr6 High Tensile Alloy High-performance race springs engineered in Germany . H&R 2.50" I.D. Race Springs are manufactured from special lightweight (hf) 54SiCr6 spring steel, offering exceptional tensile strength that allows a thinner wire for reduced weight without sacrificing durability. Key Benefits Lightweight construction: Approximately 15% lighter than comparable springs for improved unsprung mass and responsiveness. Increased travel: Delivers roughly 10% more travel versus competitors for better compliance and tuning range. Precision materials & build: German-engineered high tensile alloy for consistent performance under motorsport conditions. Pre-blocked to resist sag: Factory pre-blocked design prevents settling so rates remain consistent over time. Configurations & Applications Available as main springs (6"–18" / 80–300 mm) in a wide selection of spring rates (25 N to 700 N) to suit club, track and professional racing setups. Tender springs use trapezoidal (flat) wire with low block height to maximize travel and packaging—ideal for demanding motorsport environments and Euro-spec cars like Porsche GT3. Why Choose H&R Race Springs Comprehensive small- and large-ID program for precise corner tuning Extensive range of lengths and rates for coilover and cup applications Durable, race-ready performance with repeatable spring characteristics Optimize handling, reduce weight and extend travel with H&R 2.5" I.D. Race Springs — engineered for racers and enthusiasts who demand precise, durable suspension components.
