Come on lads

20-20 is the thinnest the shim can be (top) so 0-0 is the thickest it can be (bottom)
But when you fit them at 20-20 and the lower the beam 20-20 is no longer at the top and gives you some toe.
So you then have to turn the shim so 20-20 is at the top when the beam is lowered. Hence why you have different numbers either side but its the same camber and toe setting. Numbers always facing you.
Has that made it easier to understand?
