My testing showed I was faster if I didn't trade so much caster for camber. You'll note that if you turn the adjuster back towards the firewall 1/8 of a turn from max negative camber, you'll lose very litte camber, but gain a lot of caster. That's where I'd go with it. Also, make two or three marks - it may only rotate, but it's rubber and doesn't fit that precisely in the tower. Two or three marks will make sure you get it a bit strighter.
I also just remembered that your softer springs won't be completely unweighted when you jack the car up like my coilovers, so adjusting it might take a little more arm strength. OTOH, it might help keep the rubber centered in the tower better. Most of my problems came when I went too high with the jack and the camber kit dropped down into the tower.
