I see guys with track cars all have that setup even running stock looking wheels? Is there a benefit like making it easier to change from street tires to slicks or ???

Thanks in advance.

Closed lugnuts can get packed full of crud and the stud might bottom on the crud and not seat on the wheel. Longer studs allow the use of wheel spacers which some setups require for clearance.

plus aluminum lug nut beauty covers can get crushed or corners stripped with put on in a hurry.

the Studs are ARP hardened studs and the open ended lug nuts are also hardened.

use of spacers and yes easier to change. Plus being $1.50 or so each vs $5.00 each

The studs are manufactured by ARP and are of much harder material than the stock studs. The shortest length is 1/2" longer than a stock stud so you can not use stock lugnuts. Most folks also use hardened lugs for safety purposes. They do allow the use of spacers so offset can be adjusted for clearance around big brake calipers or to allow the use of wheels that do not have enough offset.

Interesting, I didn't figure that out either.

It's also easier to locate the wheel on the longer stud, convenient for in pit service. And most importantly, longer studs mean much more thread for loose lug nuts to travel along before coming off and allowing the wheel to do the same.

Sometimes not enough time......

I got mine because they are hardened and I needed spacers at the time. I dont use spacers anymore but it is easier to put the wheel on.

Good answers guys

I don't know if you guys have tried but it is very difficult to strip an ARP stud. Those things are hardened steel and indestructible.

Maybe a rules requirement, in SCCA series. Been a while since I looked at a rule book.

Once you strip or cross thread a stock one, especially on the rear, you'll understand why you want hardened ones!

They don't brake off like the stock ones do. Some of us are changing wheels many times. The stock ones break off.

Ding. that is the main reason.

Thanks Ted

I put the ARPs in when I had my hubs off for pilot bearing install. I ended up cutting the extra 1/2" off so I could still use my fancy lugs for street. Use open ended lugs for track days.

I had three of the longer GM hardened studs break off of the rear. I am now adding them to the yearly maintenance to do list.

That pretty much says it all right there. ARP studs are the most common thing used, if/when you go away from OEM.

for some reason the GM ones suck. I've had 2 break on me.

I swapped them all out for ARPs, and no problems in 3 years.

Kubs

Here is a question for you all. I will need to replace hubs soon. This is only the second time I have had to and I put ARP studs in at that time. When you guys replace hubs do you press out the studs and put them in the new hubs every time or just get new studs? How many times can they go in and out before you need to replace them?

wallyman424

The way I see it, the ARPs are cheap enough that you should replace them.

If theyre <1year old I'd probably reuse them, but if its more id just toss them.

Jason

I take them with me to the new hubs.
