I just installed the v2 arms. Still need to get alignment done. Not sure if I need the shims yet. I just wanted to have the shims ready when I get it aligned. I was at -0.7 front with stock arms and no shims. -2.4/-2.6 in the rear. I'm aiming for about -1.5 up front. Not sure what I'm at after switching to v2 arms. Any idea?
