My rear camber was -2.8 until I got rear camber arms and toe bolts installed. Now I am at -1.2 and 0 toe. The tire wear will be excessive at -2.8 and you should get the rear camber and toe parts sooner rather than later....
The front should be adjustable to about -1.6 each with factory components
EDIT: My apologies. What I meant to say is that the front should be about -1.6 with the drop with the factory settings. You do indeed need front camber arms to adjust. Your alignment specs indicate a serious issue with the front drivers side camber...
