based on my own experience, malalaman naman ng shop kung kailangan mo ng camber bolt dahil masyadong negative camber ang alignment. In most cases, less than 2.00" drop doesnt require a camber bolt specially kung maganda ang springs mo at hindi nag-sag. having a negative camber on the rear is not necessarily bad if you wanna reduce understeer. (refer to another thread talked about the alignment settings) Sa daily driver, -1.00 camber isnt all that bad. I have a -1.00 front and -0.75 rear
