    Bump/Rebound

    Stiffer front bump = more under steer on corner entry
    Softer front bump = more over steer on corner entry

    Stiffer rear bump = more over steer on corner exit
    Softer rear bump = more under steer on corner exit

    Stiffer front rebound = more over steer on corner exit
    Softer front rebound = more under steer on corner exit

    Stiffer rear rebound = more under steer on corner entry
    Softer rear rebound = more over steer on corner entry

    Springs hold up the car and dampers control the springs loading and unloading. The springs react to movements such as bumps and road irregularities, it's actually the springs that dampen the roads surface it's the dampers that control the timing of the springs movement.

    You have the compression cycle of a spring or bump and the extension cycle of a spring which is rebound.

    Imagine a car without dampers and just springs, if you went over a bump in the road the spring would absorb the bump in compression but continue to oscillate or move up and down (Compression and Extension) until the spring calmed down. Add dampers to the springs now you can control this oscillation or movement of the spring.

    Without a damper a spring will release it's energy from bumps in the track or kerbs say at an uncontrollable rate, dampers control the springs rate of movement or timing....Really this simple, fine adjustment of how the spring works.

    Go over a kerb and you experience a compression of the spring and the damper is now in compression or bump phase, it's going up into the wheel well, the damper is controlling the speed this spring compresses. The flip side of this is now the spring wants to release all that squished up energy and at a pretty violent rate and this is where rebound comes in, rebound damping controls the speed the spring is released.

    EXPERIMENT: Take a spring from a pen, it's really easy to compress but it sure wants to release all that energy in a hurry, you can use your two fingers and a spring from a pen to simulate how a spring and damping works, the speed you allow the spring to compress and extend is similar to controlling damping.

    How does all this fit into what i need to do to make damper changes ? That is the question race fans, i know what dampers do but what do i do with them, it's a popular question so don't worry about it.

    Um so you go into a right-hand corner, whoosh all the weight transfer goes to the left front and compresses the left front spring but also extends the right rear spring. Left front spring is in bump mode and right rear in rebound mode. As you reach apex off throttle the weight transfers off the left front a little to the left rear putting left rear in compression or bump and putting the left front into extension or rebound and right front into more rebound, the right rear kinda hovers there in rebound.

    As you get on the gas more weight is transferred from the left front to the left rear this would be rebound in the front damper and bump in the left rear damper. The weight transfer keeps moving anti-clockwise until you are accelerating straight and all the weight transfer is at the rear under compression and at rebound at the front.

    What your doing with dampers is controlling this movement or timing of the springs compression and extension as it cycles through the weight transfer from the car braking, cornering and accelerating, they also control what the car does in a straight line or what the springs are doing in a straight line, basically anytime the springs move the damper is in charge of how fast or slow it compresses and extends.

    It now gets complicated because if other settings on the car are wrong like springs rates you can be chasing damper settings forever, you really have to make sure the rest of the car is setup, dampers are a fine tune of the springs oscillations, if you don't have the car setup then it's tricky to talk dampers because you are unsure if the rest of the car is correct. I would advise to work on dampers last in testing, if you do a spring change you affect the dampers and have to reset them again for the new spring rates, very annoying.

    Just to point out dampers do not need to be the same or symmetrical values each side, they can be asymmetrical or all completely different even on the road side. I often run with just wacky numbers in the damper settings, camber settings, even spring settings i can have all four springs at different rates at a road course, who says they need to be the same front to rear
