The ST X is a ride-height-adjustable coilover kit engineered for the 2022-2024 Honda Civic (FE/FL) and 2023-2024 Acura Integra, built to balance everyday road comfort with sporty handling. Dampers and spring rates are tuned for each specific application by ST's vehicle dynamics team in Germany and built by hand at KW in Fichtenberg. The kit uses galvanized zinc-coated steel struts and a friction-optimized polyamide composite spring perch with a stainless-steel insert for corrosion-free, long-lasting height adjustment, plus an elastomer bump stop with an integrated dust-protection system to shield the chrome piston rod and seals.
