Right im gearing up to fitting my camber shims but the instructions for them are useless! My shims are double skinned so do i remove sections from both skins? Also when i decide how much tow and camber i want do i remove sections for each number on the dial, for example if i go with 20/20 do i line up the outer 20 and snip the sections out then line up the inner 20 and snip out those sections?....... Im not explaining this well!
