Wheel Stud Fitment

[bdonally]

I need to install longer wheel studs to accommodate a second set of wheels that are thicker than the Fuchs by about 4mm.
Just enough that the nuts are a turn short of full engagement.

I found Porsche part numbers, both 49mm long, (90133167100) and (PCG33167100).

There is not agreement at sellers about whether or not they will fit.
I suspect it is just a matter of whether or not these parts were used originally on a 1984 Carrera 3.2, but do all hubs use the same stud head and knurl arrangement?

Thanks

Yes.

Thanks for the info, John.

I've been to the Elephant and every other site I can find; reference to the 49mm studs I want to use is missing/in conflict.
Since the hubs are all the same, either one should work.

I remember putting longer studs in my 72 many years ago to accommodate my new Australian Superlites. As I remember after pulling the disc the fronts went in easy, the rears where a pain but I finally got them in.
