When I took the wheels off my 86,there were actually two lug nuts per stud. Seems the studs are way too long. Not sure what the PO has done here. Can someone tell me what the correct set up should be for these wheels. Do I just need shorter studs ? Thanks in advance.
It looks like you have the long-stud type hub and someone removed the spacer plate. Maybe, with those style rims there was a rubbing issue and they removed them for that reason.
Here is a picture of my 84, which has the spacer plate in place.
They probably added the extra lug-nuts to take up some space.
I bet you are now re-thinking every hard corner you've taken at high speed lately...
why the concern?
the steell lug nuts hold the wheel... the porsche OE aluminum nuts are for show to cover the threads.
why not put back the spacers and let us help you to make the tires you have fit with out rubbing. a gentle bat roll is all you probably need ..something real minor if you have anything close to stock rear wheels (C2 rims or something close with 275 tires ). those spacers are realvily cheap and will make the rear of the car look a lot better. plus you can then use the stock aluminum covered lug nuts
I have this on my '86.5. Without the spacer and bigger wheel the end of stud showed (I could not stand the look) so used open lug and bought a used set of aluminumm ones from 928intl (during the 1/2 sale no less!) cut the rounded end off and put them on. They bottom on open nut and finish the 'look'.
What size are your rear tires? I have Cup IIs on my '86.5...I left the spacers on, and it fit fine with 255s. Well...I did get some rubbing initially, but close inspection of that fender revealed a subtle ding, like maybe it had been very slightly hit. I pulled it out with my hands (i.e. it didn't do much ) but I haven't rubbed since.
Aren't you losing the benefit of the hub centric design when you do this?!?
Normally the hub centric lip is what supports the weight of the car on the wheel.
The lugs are simply in tension to keep the wheel clamped against it horizontally.
But with this little trick, all of the weight is now being supported by the lugs alone.
Maybe it's just me, but I don't think that's a very good idea...
Perhaps I misunderstood the original post...
I thought he was saying the first lug nuts were behind the wheel.
In other words, using the short nuts as the "spacer".
So we're saying both lug nuts are on the outside of the wheel..?
OK, I get it now. Sorry...

I thought the same thing - poor man's wheel spacer. Glad that wasn't the case. OP is there a lot of space between the outer edge of the tire and the fender? If so, you can add the proper width of hub-centric spacer and use the single lug nut. If not, either the wheels are not a good offset for the car or you can replace the current studs with proper length studs. What are the offsets of the wheels?
The GTS has large spacers for the OEM hub and wheels.....36mm IIRC.
When fitting wider rear wheels the spacer has to be reduced (15mm) and the studs now being too long have to be either shortend or you use the open lug nut with the stock nuts on top.
I put wider wheels with a smaller offset on mine so the spacers had to go so I just cut 20mm off the studs. But using 2 nuts on each stud can't weaken it but it would be a lot stronger because the engaged thread length is increased
Im going to measure the gap between the fender and the wheel tonight and see. I imagine I could get a small spacer in there but the studs are still going to be too long. thanks as always for all the comments and suggestions

This cannot be right !
