The Penske shocks are adjustable for low speed and high speed and you can buy the shim kit to change to any setting you want.

Also you can vary the Nitrogen pressure.... from 100# to 300# to fine tune....

The rebound is the most important control and you can change it with both the shims or get it close with the shim and use the adjuster...

They are just the best for control of the spring....especially if you change spring rates... for different tracks or conditions....

Or you can just put them on and figure out a shim pack and drive them as normal and then reach in and turn the dials and off you go to the race track....
