BMW 1 SERIES E81/E87 EXCL 1M COUPE (04-13)

BC Racing's DS Coilover system is built with digressive valving offering the same great benefits of the BR Type model and is considered a perfect choice for those who are looking for track biased coilovers. The digressive valving offers more stability and enhances cornering ability at low shaft speed which gives you a different ride from the conventional linear valving.
