Keeping in mind that repeatability is what we are really looking for, here’s a potential problem with measuring alignment on the ground…  From:

Obviously, when you get in the kart on the ground, the chassis sags and the wheels get more negative camber. However, unless you roll the kart forwards at least a metre or two, the tyres stay loaded up and don’t let the stubs sag as far as they actually will on the track. Sitting in the kart will often see camber go 2-3mm towards negative. Rolling the kart forward a few metres will see another millimetre or two of negative camber gain! Bet your mate that told you “dynamic alignments are the best” didn’t know that!”</span>
