Caster and Camber.

Jeepers, I can figure side-loads, piston speeds for ring float, mean-time to failure on Aluminium rods to mention a few things, but I am a complete dolt when it come to alignment. Here in Germany there is a dirth of shops that can deal with two eccentrics to set castor and camber. The last shop set the car up so that when it came off the rack, the front tyres looked like a John Deere row crop. I told him "that was not right." I ended up setting the thing up myself. Well, maybe setting it up at 0 degrees camber was not the best thing...no return to 0 when driving. Hoping to get an appointment at the shop that has an idea about alignment...I have the factory specifications, but can anyone give me the "compromised" specs for a correct alignment?
