I used Porsche studs to put Mercedes wheels on my syncro. The fronts were a
very light press, as you describe. The rears were a good tight press fit.

In my experience, the threads on the porsche studs don't go all the way
down to the knurl. I have to use 6mm wheel spacers if I want to mount my
steel spare wheel.

BTW, here are the notes relating to this off of my web page notepad:
8/5/99 1 hour Drilled out stud holes in wheels to 15.1 mm, chamfer and deburr.
8/18/99 Bought porsche studs. Rear 901 331 671 00 from a 65-68 911 rear
52mm (need longer). Front 911 331 671 00 from a 924 Rear Disc 79 - 82 67mm.
About $85 for 20 studs, aftermarket.
8/18/99 5 hours Install studs in front syncro hubs. These went into the hub
with light pressure indicating that a slightly larger spline would be
better. The hubs had to come off to install the studs. Machined 1/4" wheel
spacers for use on the rear with steel wheels.
8/20/99 Mil 123360 Installed rear studs, did not need to remove the hubs,
only the drums. Rear studs pressed in tight, rear studs should be longer by
5mm for full thread engagment. Machined stud contact seat with a lug nut
made into a cutting tool mounted on a stud as a pilot. Mounted Mercedes
wheels with Michelin Agilis tires (205/65 R 15 C, M&S, 102/100T, 1875 LBS
at 54 PSI) Tires ride well, small bumps are more pronounced, rolling drag
is down some, steering is much easier, sidewall flex is much reduced.
