Use a washer along with an acorn style lugnut. Just put the lugnut and washer on the stud and tighten the nut until the back of the stud is flush with the back of the hub. An impact wrench makes this a bit easier, but you should be able to do this by hand.

A follow up to this...

I just put Volk LE37K's on my car this winter (havent driven yet - sitting on jackstands). I noticed last night that there is only about 3/4" of thread available for the lugs to thread onto. I got these expensive little titanium lugs that are about 1.5" deep, and I can only thread them on about half way.

Should I get longer wheel studs? If so, from where?

Thanks for your help!

Definitely, YES! Driving the car with studs that are too short is very dangerous. If you race, they will fail you at tech inspection for this as well.

Morosso makes longer racing studs that will fit our cars. The 7/16 diameter is the one that fits the Supra. They will fit a bit tighter than stock and are a bit of a pain to get in. There is a special technique to do it without damaging anything, but it would be a lot to describe here. Email me if you get to that point and I will give you the details.

Also, since these studs are in US size and not metric, you will need new lug nuts; the kind that are open-ended so they will tighten down over a long stud. The exact style of lug nut will depend on the type wheel you have.

I just ordered 2.5" overall length wheel studs from ARP for $52 for all 20. Probably could have found them cheaper elsewhere, but I had ARP on the phone anyway, so I just ordered direct.

Anyways, for anyone that is interested -

Part # 100-7708
12mm x 1.50
.509 Knurl
2.5" length from bottom of button to tip

I will probably end up cuttin off the 1/4" thread starter and they should work perfectly.

BTW - the gal I talked to at ARP (yes, gal) was super nice and very knowledgable. I would highly recommend working with ARP if you need wheel studs or head studs....

Almost...but not correct

The Knurl on the ARP is 0.509 right? Too small

Same as the GM Motorsports 22551491 Too small

The Toyota stud is .558

They will work IF you weld them in, then re-Heat Treat
the hubs...in other words, it's a pain in the ass. I know
this from past experience.

Good luck

Badass sig, Jeff.

Powerhouse sells longer studs at $2 a pop. They are domestic size, and allow you to have a wider selection of lugnuts. Size is 7/16" i guess or something, with proper thread/pitch and knurl......I'm bad with SAE. Check their web site out.

Most of the 7/16"-20 studs have a .486 or .580 knurl (ARP)

Moroso offers .560 & .480.....also 7/16"-20

The Toyota's are .558

The .05 really makes that much difference, huh? That kind of sucks because I have these nice lugs that I would like to use with the 12 x 1.50 studs.

Do you think it is a bad idea to keep the ARP bolts with the .509 knurl? It is not too late to cancel the order...

So the moroso with the .560 knurl is the way to go, huh?

The Moroso .560 studs might work...who knows? I wasn't
willing to try them after the hassle we went through.

If you have 3/4" of thread available, this should be enough.

Titanium lug nuts:eek: kinda reminds me of the time we tried
using aluminum lug nuts
