Alignment

You're probably preloading the suspension, and the tires aren't allowing the wheels to point where they want to until you get them to roll a bit. When you lower the car off the jack, the wheels will be preloaded into a more positive camber position. They'll straiten out once you drive it a bit. Too much toe out will cause the wheels to camber negative, and too much toe in will cause them to camber positive. Start with the front eccentric all the way out, and the rear all the way in. I do my alignments myself, but if you insist on taking it to a shop, just get a carpenter's square, and set it next to the wheel and measure from it to a flat part of the outside of the rim. The measurement should be the same at the top and the bottom if the wheel is at zero camber. If the top of the wheel is too far out, bring the front eccentric in. If the top of the wheel is too far in, bring the rear eccentric out. Then check the toe, and set if for 1/16" toe in. Then drive the car 100' or so, and make a few turns to settle things in, and then check again. If you want 1degree negative camber, set the wheel so the top is 3/8" in farther then the bottom of the wheel.
