5.4 Rebound Adjustment The rebound adjustment (also called droop) varies the damping of the downward travel of the wheel relative to the vehicle. The rebound adjuster is located on top of the piston rod and has 19 damping positions. Depending on vehicle ride height, the car may need to be raised to gain access to the rebound adjuster. To adjust the rebound damping, turn the upper finger knob: clockwise stiffens; counterclockwise softens when viewed from above. All settings are referenced from the full stiff (position "0"). The "0" position on rebound is achieved by turning the finger knob clockwise until you cannot turn it any further.  AUTION: To avoid damage to your C dampers DO NOT force the finger knob when it stops turning. Also, NEVER use any tools to adjust the finger knob. From the "0" position, turning the adjuster counterclockwise will soften the damping. Every "click" is a new damping position (i.e. two clicks softer from the full stiff position is position "2"). + - Hard Soft 5.5 Street Set up Best Comfort is achieved at the following damper settings and should always be used when driving on the street: Front: Compression = Position "13" Rebound = Position "18" Rear: Compression = Position "13" Rebound = Position "17"
