Set Castor
Set Camber
Set Toe
As long as you don't make huge changes in camber or toe, then there should be no need to check Camber after setting it correctly. BUT large changes in Camber and toe can throw the other off. Using a Proline you can check both at the same time, which is why we use it.
Rear pills or adjustments are always set before adjusting the front, unless we decide to try something different then the front is checked to see how much it changed if at all. Then we scale for percentages from there.
