So let me get this straight. You spend time, money and add 1.5 lbs of unsprung weight per corner to push the wheels out less than 5/8 of an inch. For vanity.
You sure you bought the right car? Sounds like owners of Hondas, WRX's and the like.

Hi;
Yes I did.
For various reasons. Wanted wheel studs / nuts, always do this conversion on my cars. Wheel assembly is easier and so protects the ceramic brake discs.
Like the BBC BBS wheel nuts. They be art for me. :-) Also find that the wheels are much more consistent in the wheelhouse.
Likes little details like that. That's all.
@Sevenhead
Maybe i am wrong, what you derive from such a small technical change, is fascinating.
Your post sounds like criticism? Wrong car? You imply vanity?
If owners of Hondas WRX's like it too, why not?
It's really vain to put yourself above other people, just because of a vehicle.
By the way, I know great people who don't even have a car. :-) :-) :-)
Tolerance is the magic word. :-) :-) :-)
Best regards

do you have any pictures of your car with the spacers on? Do you get many stone chips?
Has anyone added spacers to their GTR? Does it effect the handling characteristics negatively?
Secondly - lowering the GTR - has anyone done this on the stock set up? Thoughts?
Any pics would be appreciated….
My Video that Stenzel posted has plenty of pictures.
I've had them on for all of this year and haven't had any issues. Did some drag racing, roll-racing and drove her plenty and frankly forgot they were there. Got a flat after running over a nasty nail. When I had the tire fixed, I then remembered they were there. Very seamless experience.
Stenzel - you are one tolerant and thoughtful person in so many ways...I could learn a thing or two. I wanted to rip out at mr. sevenhead for his keyboard courage but you handled him nicely.
Always nice to have other options for convenience, thank you Stenzel
Curious though, regarding selection of Aluminum alloy for lug nut, which is a critical fastener.
My only concern is for ?potential safety/durability issues (especially during sustained high loads and elevated temps, on track, etc) :
Aluminum and its subsequent alloys typically have (significantly) lower modulus of elasticity than Steel, for any given load.
In addition, they also have higher coefficient of thermal expansion than Steel.
Anecdotal evidence via Wasserott et al suggests they are sufficient for typical road use and the occasional pull/drag race, but how well will they withstand more punishment during higher sustained loads/higher temps?
Any other data points from other users?
Porsche had used OEM Aluminum lug nuts in their earlier models (but i believe with lower tightening torque specs and lower engine hp/tq).
The GT lug nuts are also subject to relatively high tightening torque of 180 Nm (for GT x, per manual specs).
The aluminum wheel nuts used are made for / by BBC BBS (a very well-known wheel manufacturer from Germany) and be offered for Porsche.
The fine thread is continuous and long. (approx. 2.5 x d) That is sufficient for aluminium. There are very tough aluminum alloys. Trust BBC BBS here.
About torque:
Find 180 Nm just too much. M14 x 1.5 wheel bolts are normally tightened to 130 Nm. I set the torque to 150Nm. (It's absolutely fine for me, but shouldn't be a general recommendation here)
But this decision has nothing to do with the aluminum wheel nuts. I also tested 180Nm on these. (Sell 3 sets) No problem.
Can understand your concerns. Especially in racing. I don't have these concerns.
If you prefer steel. My 1st set was easier. 90mm wheel studs, the steel sleeves removed from the stock wheel bolts. Wheel nuts from the MB Sprinter 4.5 ton.
These are black, flat collar nuts. Like it, but the BBC BBS nuts just so great.
Fun story: Why i "made" 4 sets.
I always do wheel studs with nuts on my cars.
First the "Sprinter" version. Then I found the BBC BBS lock nuts and black studs with stepped tips.
The BBC BBS nuts are normally a set of 4 porsche wheel locks. Ok. 5 sets ordered fot the required 20 pieces. Arrived. Very nice. Like it.
Then I had (little late) the thought, what if a nut is broken, scratched, or lost? Can you still get these? Ordered another set of 4 locknuts, as replacement parts.
That came quickly. However, I had to find out that it had a different coding. The first 5 sets were all the same. (Think that is normal)
After a nice conversation with a friendly lady, she informed me that this was pure coincidence, as the nut sets are supplied in different codings. Unsorted.
But with a little time, she could search the right codes for me. Great.
Send back? No this willingness to help, should be rewarded. So I ordered another 20 studs, 4 spacers, and 6 locknut sets with the desired codings.
Ordered at night and paid immediately. Unfortunately, the shipping department was too quick. (Order was here, payment was done, package goes quick out)
In itself, commendable, but they knew nothing about the agreement. Now I had 12 locknut sets in now 4 different codings. :-) :-)
After further discussions with the friendly lady, I ordered another 40 studs, 8 spacers and 12 locknut sets. This is, how you can generate sales. :-)
The coding then fitted through the personal commitment of "Erika". Expect a Christmas card.
Still turned the matching 96 slaves, and 4 sets were complete.
The 3 left over sets gone quickly. One became chuck.
The hourly wage was really bad, but win a new love. -> Erika .. :-) :-)
Kind regards.

I believe the name of the wheel company is BBS. And they are very well regarded especially in the racing world, probably second only to O.Z.
You hadn't done anything wrong. It is your opinion.
Just maybe some "pejorative" words chosen.
The only bad thing would be if a difference of opinion escalated.
Which should never happen.
Your "weight objection" about the spacers is also correct. But you have a larger track width.
Is it better? No idea. In any case, it looks better to me. :-) :-)
Got a few requests via PM if I can supply these set.
Sign up here if you are seriously interested. If there is enough interest, I will look at the current conditions.
I can buy studs, nuts and spacers. I have to drill out the nuts (taped studs). Manufacture the sleeves on the lathe.
For Sevenhead: If you don't want spacers, just shorter studs, sleeves and nuts. :-) :-)
I do things like that in my spare time and I'm not a mail order company.
So it will take a longer time. It will be expensive for that. :-):-):-)
Best regards
Stenzel
have you lowered the car too? My experience from other cars (Porsche and BMW M cars) is that adding spacers generally only looks good if the arch gap is reduced (my opinion obviously not fact).
the GTR stance is great stock but I feel I would need to lower it 10 or 20mm to reduce the arch gap?
Hi, Of course you have to take the wheels off. :-) You also need the appropriate "hook wrenches" I have these in my shop equipment:  Not 90mm bolts. If you want normal wheel bolts instead of studs and nuts (with stock rims): Bolt:Head: "Kugelkopf" ballcollar? radius: R14mm)Thread:M14 x 1.5Length: 27mm (stock) + 15mm (spacer) = min. 42mm - max. 45mm General wheel bolt infos: Tread be measured from thread end to ball collar. Minimum screw-in depth:M14 x 1.5 = 7.5 turns (All GT)M12 x 1.5 = 6.5 turns Spacers:High: 15mmBold circle: 5 x 112mmCentering: 66,6 mm H&R works. (and all other brands)Recommend SCC, these are more stable in the centering than the H&R. (Own experience) Best regards Stenzel
thanks for this. Knowledge of all as usual
Did you not get concerned about the change to suspension geometry and scrub radius etc? Additional stresses etc?
Or is 15mm too small a change to make a difference?
Yes I did.

Haha. Love it, Stenzel. Imagine a world where people judge negatively anyone / everyone who has different opinions and perspectives. Oh, wait, that is this world Oh, well. At least we also have tolerant, logical, and kind people in balance who add more than they take away. I think it's clear who had the wrong car if not the wrong forum. :o)
