The GP-1 Digressive Coilover is different than the linear valved system in terms of damper valving. This means the damper has much more low speed control in comparison to a Linear valve. This is due to the low flow rate at low shaft speeds. The resistance rate increases as shaft speeds increase, but only to a pre-determined level, whereas the Linear variant continues to increase. The digressive valving then has resistance that tapers off and as the shaft speed continues to increase, the resistance remains constant. This eliminates unnecessary resistance and provides more control as the vehicle encounters irregularities in the road??'s surface. This setup will do a better job of managing unwanted body motions while also still providing a comfortable ride.

The digressive coilover system is great for street use, canyon carving, and track days.
