Using a piece of 1.5 x 1.5 x 1/8" angle iron with a digital level attached makes a very simple and effective camber gauge. The ends can be modified depending on the wheel. This works well for AP2 v1 wheels that do not have andy protruding spokes. It will not work as-is for AP1 wheel with out being adapted. It works well with 949 6ULR wheels too.
