Damping:
Tuning your car's damping improves handling by increasing grip. Stiffening front damping adds grip at the rear. Damping controls the suspension's rate of travel in two directions. Bump damping controls the rate of compression as the suspension goes up into the wheel wells. Increasing front bump damping stiffness increases transitional understeer, but excessive bump damping can make a car skittish over rough surfaces. Decreasing front bump damping stiffness increases transitional oversteer. Rebound damping controls the rate of extension as the suspension rebounds away from the wheel wells. Adjusting front rebound damping fine-tunes your car's balance going into and out of the corners.

Increasing front rebound damping stiffness increases transitional understeer. Decreasing front rebound damping stiffness increases transitional oversteer. You might try different damping siffness front and rear. First, set the overall damping stiffness, and then set the bump ratio. Bump damping should be 50-75% as stiff as rebound damping so the car will start to squat before rebound makes it stand up. Otherwise, the inside tire will lift off the road. Experiment by increasing bump stiffness to find the best damping ratio for your car.

Do any of you guys tune for this? What measures most be taken to adjust this on the Riv? Am I the last to hear about damping?

How/why does increasing damping stiffness increase understeer?
