i'm looking at wheel studs for my discs as stepping up to 5x130. i can see quite a few, press-in (which i can't do myself) or screw-in (needs a good drop of loctite IMO).
does anyone have any experience with these?

also, i find various sizes :

Whatever you want. No screw-ins !!! Torquing up alloys to 10 Mkg will either strip the nut/and or stud or pull the whole thing out. That's why their called "screw-i......

Press in for sure! I know someone that lost a wheel at the track.

SAW makes a nice set, the Bugpack are o.k. too. 14mm for sure. The length will depend on spacers or not. Measure up and you will know. The shorter ones are good without spacers.

If you run the Mag lug nuts, factory porsche, you may need to trim the ends of the studs or they will "pop" the top off the lug nut.

P-

The problem with buying studs is that the sellers sometimes don't know how to measure a stud.  You almost have to have it in your hand with a ruler to be sure you get the right one.  These studs above are most likely measured by their overall length.  The correct way the rest of the entire world uses is from the underside of the head.  Many of the studs (I think these ones too) have an unthreaded portion at the end.  As stated above, if you use original P type Al nuts, you have to cut off that worthless part.  Then what's the real length?  Nobody knows. 
Whatever stud you pick, get on the phone and don't hang up until the guy on the other end has put a ruler on it, measuring from the underside of the head to the extent of the threads.  Hopefully one in mm.

Porsches came equipped with studs extending from the rotors by 30mm.  You can get away with 2-3mm more.  Add the thickness of your rotors where the holes go, there's the length you need.  Spacers?  Add that. 

just a reminder, check the serrated portion of the stud. OD diam.  and you drill size or hole. be sure it is not to tight of a press fit. I have seen drums crack when pressing them in.
You will find the empi, bugpack and porsche or if you have access to a dorman catolog there are several different sizes.  (dorman catolog has several under 14mm and it gives you the shouldler/serrated height and threaded lenght.

I have used the long 65mm porsche studs....not cheap but good quality.
the bug pack ones are good, the empi ones vary to much from one to another.

If you use press-in studs , Make sure you countersink holes on face of rotor a little heavy> Why, so when you press the stud in, The material raise's alittle from press , Then the front surface has small high spots  around stud
