Add SPC 81260 camber bolts in the top position and add -1.5 camber, set toe to 0. Get a 4 wheel base alignment just to get an idea what all the wheels are doing. It's possible your rear toe will be out of spec. The geometry of the beam on a lowered Fit can cause the toe in to increase, as well as how the tech person pulls the car onto the table. The compliance bushings can give a false reading so don't sweat a slightly out of spec rear alignment as the torsion beam tends to correct itself in the bushings. There's no easy way to change rear alignment settings.

I found -1.7 in front actually helped me get a more even tire wear. Rear stock will be in the -1.3 to -1.6 or so.

 

Toe in or toe out is what accelerates tire wear. -2.0 or less camber will be negligible.

 

aim for about -1 in the front, and feel free to do about -.05* toe out in the front... it'll help it turn in.

check the tire wear before and after about 2k and adjust as needed
