Notes
* increasing or decreasing LR rebound more than RR will have a greater effect on entry and exit
** Overall stiffer front springs will make the car tight. Softer front will loosen the car. Overall stiffer rear springs will make the car loose. Softer rear will tighten the car.
*** Increase cross weight by increasing RF/LR spring or ride height or decreasing LF/RR spring or ride height. Opposite will decrease cross weight.
