H&R ID race springs for 2017–2019 Porsche 911 (991) GT3 RS are manufactured from special (hf) 54SiCr6 spring steel to reduce weight and increase travel compared with conventional springs. The race-spec line offers a wide range of lengths and rates, includes tender spring options, and comes pre-blocked at the factory to resist setting or sag. These springs are aimed at demanding motorsport tuning and custom suspension setups.
