set back: ----- ------ -------
camber: -1'35" -1'20" -1'05"
thrust angle: -0'15" +0'00" +0'15"
also the only thing it changes is the set back... how far forward or back it sits, as the lower you go it pushs its self back.
set back is how far a wheels position is compared to the opposite wheel on the same axle, usualy measured in 100ths of a mm or in degrees across the axle.
it alters the wheel base on the car, some cars i have done can be as much as 3 or 4 mm out----usually bent wishbones (ford) or even axle beams (corsas)
drive behind a car thats "crabbing"---thats exagerated setback !!!
