What are the four adjustments?
Jack, They are:
Low speed rebound - This helps with driver feel and helps keep the platform stable. Going too aggressive will make the car feel harsh and choppy, finding the balance here is the key.
Low speed compression (bump) - This will help with getting the tires up to temperature quickly. Basically it helps to control how the unsprung weight of the car is controlled. Ideally you want to run as much as possible to where the car is not unsettled on the lager bumps on the salt.
High speed rebound - This helps to control the spring and how the body is moving after hitting larger bumps. Here you want to run little as you have to so the car docent "jack down" while going down the salt.
High speed compression - Again here you want to run as much as you can get away with without going too stiff. If you set it up too aggressive the car can launch when you hit the bigger bumps on the salt.
Walking around the pits I here people complaining how the car did this or that and the salt is bad. In my opinion a majority of the time the car was not set up properly. Every time the salt is bad there are a bunch of cars that go fast and set records. hmm Tony
