Notes
* increasing or decreasing LR rebound more than RR will have a greater effect on entry and exit
** Most oval cars require approximately a two‐degree split in caster left to right, with the left front running a lower caster setting than the right.
***Increase cross weight by increasing RF/LR spring or ride height or decreasing LF/RR spring or ride height. Opposite will decrease cross weight.
**** if lowering the front ride hights the intent is to seal off the splitter to the track, going too low will result in the splitter hitting the track which will cause less grip.
