The DS Series coilover kit by BC Racing are essentially an “entry level” track kit, with the most notable feature being the digressive valved dampers.
Digressive valving is often used for track suspension as it gives you more feel over the car at low piston speeds (small bumps), while retaining stability at high piston speeds (big bumps). This makes them good for track driving.
Aside from that they come with all the usual features of the BR Series coilovers.
The DS Series coilovers are great low cost option for occasional track days and autocross events while still being street usable.
