I know this topic is on the wrong board, but since somebody started it, I have a follow-up question.
I also have a prokit sitting on 18 inch rims, and aligned the car a few day ago. The readout were

left front;-1 right front;-1.5
left rear;-1.4 right rear;-2.3

The guy at the alignment shop told me I just need to add 1 or more washer on the right rear (I did $15 camber mod). The fronts are a little bit out of spec, but since the toe was set right, and the front wheels are moving a lot, I really don't need to get a camber kit. He said I just need to rotate the wheels often.

Is he correct or bull-shitting?

Once again, sorry for the wrong topic on this board.

Thanks in advance.
