911 GT3 string alignment

I have a question for anyone with experience performing string alignments on Porsche 911 GT3s with camber adjustment on the upper portion of the wheel bearing housing on the front axle. How are you making camber adjustments at the upper eccentrics with the string alignment system on the car? It seems like the only way to access the eccentrics is to remove the wheel, make the camber adjustment, put the wheel back on, and measure the camber again after settling the suspension. This feels like a very time consuming process of trial and error and I would like to skip the guess work and make educated decisions. The best way I can see solving this issue is to perform the alignment with hub stands, but that's not exactly available for me at the moment. Any suggestions? Thanks!

If I were faced with that situation, I would find a way to measure the camber while the car is without wheels. Perhaps you could determine that at full droop, you loose 2 deg of camber, so you could measure the camber at full droop, and add your change to that value (so not much of a guess), then put it on the wheels, settle the suspension and measure the resulting camber.

If this worked out, you could do all your alignments while the car is without wheels at full droop, you only do a confirmation measurement after you were done.

Yea, that seems like the most logical step that I was missing. Thanks for the tip. I'm going to perform some measurements and see what I end up with.
