All of the above plus separate damping adjustability for High Speed Compression, Low Speed Compression, and Rebound. Low speed compression damping adjustability allows you to fine tune chassis movement on the compression stroke over round bumps and/or throttle and braking inputs. High speed compression adjustability allows you to fine tune bottoming resistance and wheel movement on the compression stroke over rumble strips and square edge bumps.
For drifting, road racing, auto x, and other tarmac motorsport applications.
