Al from CPT told me... (when I enquired info on their tie bars for our cars, imo these tiebars just can't be beat neither on looks nor quality..cheap too) ... that if you if you want to adjust BOTH camber and toe to a 100% setting, you had to install adjustable bars at both the upper AND lower position?! According to him, if you install them in the lower position you can only correct camber and you install them in the upper position you can only correct toe. Correcting he said, as in adjusting them to a full extent (100% to your liking), not just what is possible f.ex. like me, I wanted -1.00 degree camber 0.00 degrees toe at the rear axle but the mechanic couldn't manage that. He couldn't get closer than 0.04 degrees (camber was -1.00 tho)... Is he right?
