Basically you want the least amount of TOE on each tire. Then camber and caster set at mid spec, but importanly BALANCED side to side on each axle. (dont set toe to 0.00, as it will tend to wander, but 0.01 0.02 toe in)
Pretty simple.
If you are tracking the car, well, then you know how to set up a car for track and dont need my advice.
The thread is a bit long, but it is kind of a 'teach a man to fish' thread...WHY we have the specs from BMW, WHY there is so much BS and mystique around the specs. etc etc
