You want the rear lower bushing maxed out for neg camber, which is also max caster for this adjustment. Front bolt is moved inward (pos camber) to increase caster... but likely only slight adjustment inward from max. Can also stagger upper shim thickness with more on front upper to increase caster.

So just to be clear on the words, "maxed out" in this case means 180 degrees opposite of what my diagram shows, correct?

Sorry for being so redundant.

Max is bolt positioned closest to tire... max neg camber.

Max out both bottom eccentrics and do all your adjustment on the upper arm with shims.

Depending on your caster target, I don't like "kinking" any adjustment too much. If you maxed both lowers would have to really stagger upper. For example on C5 I'm at -2.5 and 7.8 with minor front shim and maybe 30deg from max in front lower.

HI, I am actually NOT looking to change caster at all & can live with .1 to .3 change in either direction.

want to get about -2.5f and -1.5 rear like my c5.
