ok so I have sat and had a word with myself
think I sussed the C mounting inserts, didnt help that I have B5m and B6 inserts DOH both marked differently
anyway
let just make up an example, with plastic D mount all rear mounts are central and the C mount is adjusted, figures in the manual for toe and squat
if for example I have it setup for 2 degree toe in, 1 degree squat, and then used a 0.5 degree rear insert in the same orientation, would that therefore give me 1.5 degree toe in?
