H&R Sport Springs lower the 981/718 Porsche Boxster and Cayman (PASM-compatible) for a tighter, more aggressive stance: roughly 1.0" front and 1.0" rear on Boxster models and 1.2" front and 1.3" rear on Cayman models. The progressive spring rate reduces body roll and lowers the center of gravity while keeping street comfort, working with the factory dampers. Made in Germany from cold-formed 54SiCr6 spring steel.
