Bilstein EVO Series coilovers are the next step in the evolution of performance suspension tuning. EVO T1 is a coilover kit built and tuned specifically for everyday street use and occasional track duty. Featuring ride height adjustability and manually adjustable performance dampers. The 10 - stage damping system adjusts both rebound and compression to provide the best handling performance for both street and track conditions. Redesigned threaded bodied dampers allow for extreme lowering of up to 70mm. High quality components provide consistent performance for every adjustment. Greater stability, traction and higher cornering speeds are achieved through specific application tuning. Bilstein EVO Series suspension kits are designed and built in Germany with technology tested and tuned on the Nrburgring.
