BC Racing's digressive piston design offers increased dampening force at low piston velocities while maintaining a linear damper feel at higher piston velocities. One of the greatest advantages of increased low-speed dampening force relates to what the driver feels, example; roll, pitch, dive, and quick weight transitions on technical road courses.
