I believe this is correct answer.
One stud is marked because wheels can be balanced while they are mounted in car. Not sure what is procedures correct name in english. Rolling road balancing perhaps? Nowdays only few places can do it. There is really no need for it anymore as rotating parts like brake disks are so well balanced internally already and wheel balancing machines give good results also. Anyway, manual asks wheels to be mounted into same position every time in case they were balanced while mounted into car. This will quarantee correct balancing when wheels are taken off and put back later on, for instance when separate summer and winter tires are used on different set of wheels.

N!
We'll make a party of it! Always fun to see you. You driving or flying up?
P.S. You do know that the crest is supposed to point to the valve stem, right? The shame... oh the shame!

The valve stem is supposed to be located 180 degrees of this stud. This is why ...say on 5 spoke, the valve stem is in between the spokes....holes are in the spokes. At least this is the way it is on OE Porsche wheels.
If the paint is gone, you can figure it out by locating the 2 screw heads on the rotor hat. These screws have two lugs between them. The valve stem should be located between these two lugs. Porsche crests in the center caps should have the bottoms pointing directly at the valve stem!
Factory wheel locks can now be located on the painted (colored) stud to balance the whole contraption.

I just changed my air in my tires this past weekend for some new spring air.....Works great! Much better performance, better fuel economy becuse the air is more dense.
