rear camber adjustment

Question one: On my 87 which way CW or CCW should the adjustment cam be rotated to add rear camber? I have about -4 now but want to straighten it up to save tires.
Question two: What is the concenses on good camber setting? I have seen vettes around town with a huge negative camber to very square 0 degrees and even a few positive.
Good even tire wear or tight turns???

I was running about 1* - 1.5* negitive on my 85 street/autocross and it didn't seem to hurt my tire life. VB&P has good baseline settings, check those out. Remember when you switch your camber your toe-in is going to be all screwed up and needing adjusting (both front and rear).

-1, I had it up in the air last weekend to do some brake work and when it came time to straighten the wheel I coudnt remember which way to turn it and didnt want to make it worse.
I just only want to do it once to get it tracking again. When I have the time I take it to my local goodyear and get four wheel alinged.
Thanks for the info.
