What controls the rate which the tires absorb large changes in the pavement (i.e., speed bumps)?

I want the chassis to not 'fall' as far and/or the front tire to not raise as far into the fenderwell on these types of surfaces. I need to work around the exhaust clearance (or lack thereof).

My setup:

Front:
Koni DA's
Stock springs (73K miles)
32mm sway bar
tubular upper a-arms

Rear:
Koni DA's
Stock springs (73K miles)
stock sway bar
Hotchkis boxed LCA's
Hotchkis panhard

The compression adjustment (the rotary **** on the bottom of your Koni's) adjusts how fast the wheel compresses towards the chassis (or how fast the chassis drops toward the wheels). This brings an interesting choice, too stiff and you will raise the body ("jacking")over bumps and then the weight of the car will drop after the car drops over the bump. It's a compromise, but I'd try an extra click or so and see how it does....good luck!
