They do offer open ended ones as well, so no cutting required, right?

No, he’s referring to the studs I believe. ARP studs (like OEM) have bullet ends- rounded off and not threaded, a feature I really like.

I see...so what would be the benefit of cuting them off?
Seems counter intuitive to me. The other suggested studs seem to have even longer bullet like (unthreaded) ends...Anyhow, hope RUQWKR will clarify his post.
Thanks!

Depending on what wheel / spacer (if any) combo, if you want to run stock style CLOSED end lug nuts, you can buy yourself another ~12mm by cutting the bullet nose off. Not every combo would require that of course.

Like the OEM studs, the bullet nose helps with getting the lug straight before engaging the first thread. However, I would hope all of us finger starts the lug nuts enough to ensure no cross-threading. I have ARP's up front with the bullet nose cut off as a just in case I run a wheel / spacer combo and wanted to run the stock style closed lug nuts. I've only been running stock SS / ZL1 1LE 20" / 19" wheels, so, I have not needed the extra threads on the ARP's. I cut the noses off before installing the studs back when I swapped to J6H / ZL1 brakes and was going to have the SS 1LE rotor off the hub.

FYI - I like the looks better with closed end lug nuts and don’t have thread engagement (amount of) issues [14mm or greater for my piece of mind], nor do I have a tech inspection need that some may have.

They are MSI and we've had excellent luck with them.

Kind regards,

Thanks! So, no spacers needed for zl1 1le rims and hence zero mods other than strut grinding, eh?
Given Provoste's pace with 305/325 combo...this is a tempting option, albeit 305 22et does present its own merits. Hmmm....

Correct - just normal grinding. 315/30/19 Hoosiers fit as well up front on 19x11 +11 OEM rims with no spacers.

Speaking of studs, L to R, an ARP next to stock, MSI on the right and a PTC on the bottom. The PTC is made for a F-250 etc, so it's a probably not going to be used by me.

That is an ARP 100-7736 (1/2" longer thread & overall). The -7737 are 1" longer thread & overall if you need to go that route.

Also, as you can see from the stock stud that was used with a stock wheel, there were 9 threads engaged or just below 14mm engagement which is the minimum I shoot for, but, lots of opinions on that.

Beware buying lug nuts from Amazon. I bought Gorilla brand ones and when I opened the box it was obvious the plastic bag has been opened before and I could see rust dust. When I inspected the threads you could see rust on the threads. I checked to see if I could thread the ARP studs in and only 6 out of the 20 could be threaded all the way.

Thanks for the heads up!

Test fit is looking good. Waiting for tires now

Test drive today with the Provoste 305 square setup with G3R tires. It does poke a little but makes it look even more race car
