Set your ride height first with whatever tires you're going to use.
After that, set your camber and toe, in that order, because camber adjustment will affect toe.
The difference in ride height on the stands isn't going to make a difference, and the hudy stands don't measure caster, so the only measurement that might possibly be off a touch is going to be camber by just a hair.
If knowing that is going to bug you, I'd recommend setting your ride height and camber with the tires you're going to run, and use the stands to set toe, but I haven't found it to be enough difference to worry about.
Privateer racing lots of stuff.
Remember kids, racing isn't fair!
