1986 Porsche 928 - Strange Lug Nut Problem
Hey all...
I got what I think are a nice set of Steel luggz on eBay, correct and matching tapper - ball seat type. But it seems they are not deep enough for the rears where I have a spacer with its own lug bolts. Literally just 4 to give threads to short. Tighten them all the way down and there is play in the wheel... Crazy!
What sized lugzz,,, and where do you get them,,, if running rear wheel spacers? Any advise, suggestions and direct is much and super appreciated! Thanks.

Its not the spacer thats the problem, its the extended wheel studs used, IMHO. Measure them, compare to the fronts, check the depth of the lugzz. VW lug nuts are same thread - M14x1.5, and are open ended.

IF you have wheel clearance at the fender lip...you can remove the existing spacer which I believe is 21MM and perhaps try a larger spacer, 25mm or 30mm. The wider stance tends to look more contemporary too.
This item should work but you wont use the bolts.

It sounds to me like he originally had the factory 21mm spacers and associated long wheel studs. I believe he has removed the factory spacer and replaced them with bolt on spacers, which the studs are too long for.
What is the final spacer measurement you are trying to achieve?

Hello all. Brenna busy day and I'm sorry I haven't responded...
I have 21mm spacers and I believe what is a 1inch spacer, bolt on, with its own bolts... Came with the car.
I order closed end ball based luggz that fit and work perfectly on the front, but not, sadly, on the rear. I was hoping there was a slightly larger/deeper ball end lug that folks had been working with...? Anything like that?
I don't want to run with open ended lugz. These shiny steel ones look really nice. Shoot, my WILD side says get a skinny cut off wheel for the grinder and take off 4 threads or so... Solved, lol
Oh yeah, edit --- it's not toooo spacey

dont cut those studs,
you will ruin the wheel bearing to replace them.
That said lets back up a bit,
please post pictures of what your trying to make happen.
To figure out what spacer size you need put the wheels on,
then measure the fender lip inner edge to the side of the tire.
do both sides, then subtract 5 MM from the the side thats closer,
This will be your target spacer size, you can go thinner but not thicker
you will ruin the wheel bearing to replace them.

Problem is, with everything as it is,,, the new lugz are too shallow. I need deeper lug nuts...
What did you mean when you said?:
"dont cut those studs, you will ruin the wheel bearing to replace them"
Edit --- ok, I get what you're saying now, Merlin

He's referring to the factory long wheel studs installed on the car to incorporate the factory 21mm spacers. the issue is possible damage to the wheel bearings if you have to hammer them out to replace them (bearings don't like the impact). You may want to consider removing the stacked spacer that you currently have and install a single bolt-on spacer of the combined thickness. you would install the bolt-on spacer with open lug nuts, then the spacer i would think should have the correct length studs to allow for the installation of the wheel with standard closed end lug nuts.

you cant remove the studs without removing the wheel flange,
if you remove the flange then the bearing is destroyed .
That said do not use 2 spacers back to back,
put the factory 21mm spacer on then follow the measurement guide i posted then .
Figure out how much more room you have then add that number to the original 21mm spacer then that will be your target spacer so you will be buying a new set of bolt on spacers,
you can sell the non factory spacers
Please before you do anything post pictures of what your doing,
you will get waaay better answers

I'll post some pictures next time I have the wheel off. At work now.
The spacers that came with the car I am keeping... Doubled. 21mm inside and 3/4 or 1 inch outside... The car sits right. I have been running it this way (not for too long but for a little while,,, she is new to me) I like the look and I don't get rubbing on the wheel and arch...
I am simply trying to install a new set of Steel lug nuts. The old aluminum ones were looking chipped and ratty... Turning the steel luggz in, they were/are not deep enough, and the cap bottomed on the bolts without properly capturing the wheel to the spindal/hub. Maybe 4 or 5 turns shy of capture to torque.
The bolts installed at the flange are the 72mm to account for the spacers...
I went back to the aluminum luggz, for now.
I have ordered a set of open ended ball luggz. Will turn them in and see what the new steel luggz look like on top of them. If that doesn't work (of the steel luggz extend to far out) I have order a die, m14 1.5, and will run the die down the bolts and make my cut, bolts on the car. Maybe using the die as my guide. Then, turn the die out and file as needed to clean things up on the bolts post cut...
For me,,, this work is a joy. I am not panicked... Some experimenting is ok. No stress for fun. I like to take things easy...
We'll see how it goes...

Lug Nuts - Ball Seat?
Anyone have any good after market "Ball Seat" lug nuts for the 928?
I'm looking for "open" in black as well as "steel, chrome, zinc."
Can cone/acorn/tapered seat lug nuts be used? It looks like 96 lb/ft of torque? Will it be secure enough?
