It is literally all about your car and what it wants. No one else's car is going to have the exact same settings as your would. The shock settings in many cars that do enough testing and racing might have a setting for a certain track at a certain time of the day and change later in the day or when they go to another track. I've worked on cars where I changed the shock setting every pass. You have to play with them and see what the car does and see what it likes. It will be a totally different set up on a ladder bar then a 4 link.
