Turning the adjustment sleeves on the upper control arms is the correct way to adjust camber. A similar arrangement adjusts rear toe as well. Adjustments are very fine. I usually turn the sleeve one or two "flats" of the hex, then measure. With enough practice, I'm pretty well able to do these adjustments with standard 15/16" and 1" open-end wrenches, but the rear toe requires removing the wheel/tire.
The early UK cars do not have adjustment sleeves, and require the heim joint to be unbolted from the upright and turned in 180 degree increments. Iâ??m not sure about the Atom 3.
I use Longacre camber gage and toe plates.

I initially tried using a digital camber gage similar to this, but found that the wheel rims on the TD and Dymag wheels had so much taper, I could not get consistent results.
The TD, Dymag and SSR wheels I have all have a nice flat center hub area which accepts the magnetic gage nicely. Of course, the magnet is of no particular use, since the wheels are non-ferrous alloy.
