The only thing it technically should change is camber...so unless you have a camber kit...then don't even worry about it. If you do have a camber kit you could even eyeball the camber and get it pretty close to where you want it. There is some leeway in camber spec unlike toe settings. Toe you want perfect or you'll eat tires. Camber spec is 0 to -1.5 I think in rear, and the rear is what's gonna change a lot. Front won't change much until you are lower than 2".
