RS*R XBIT591MA Best-i Active Coilovers for Lexus IS350 F Sport RWD

The RS*R Best-i Active Coilovers are engineered to work seamlessly with the factory Dynamic Digital Suspension (DDS) system found on 2021-2024 Lexus IS350 F Sport RWD models. Unlike traditional aftermarket coilovers that disable the DDS system, the Best-i Active series retains these factory controls, allowing the factory actuator to function normally with aftermarket coilover performance.
