Camber bolts go in the top hole. The way to look at it is that the camber bolts will pull the top of the suspension knuckle inwards to give you negative camber.
I'm in the same situation as you. Please, please tell me what is the max negative camber you can get up front with those camber bolts. I have maxxed at -1.3 front and -1.0 rear, but I really want -2.0 up front.
