Bilstein EVO T1 is a height- and damping-adjustable coilover kit tuned for everyday street use and occasional track duty on the BMW Z4 and Toyota GR Supra. The Dual-Click 10-stage damping system adjusts rebound and compression together via an aluminum dial, and the threaded-body dampers allow lowering of up to 70mm. Bilstein EVO Series kits are designed and built in Germany and tuned on the Nürburgring.
