Where can i get a set of open lug nuts for a C6 Z06...any recommendations from supporting vendors?

exracer28

NAPA carries them in stock. Ask for 2002 lug nuts

I suggest you contact CCW. They're absolutely first rate in every respect.

Just about any parts store will have open-ended lug nuts. The stud diameter, thread pitch, and the taper degree are the same for the C6 as for most any late GM car that had alloy wheels and metric studs. C5 and C4 cars use the same specs for lug nuts.

Here's some. With threaded shank.

Just don't pick up the stock GM open ended lugs. I bought a set last year and I bet I didn't get three events out of them before they started rounding off

I will probly pick up a set from NAPA this year.

ANY local Advance/Autozone should have them. They are usually behind the counter, not out with the fancy wheel accesories.

I am surprised to hear that. I am currently using some gm ones that I bought when I started autox my LT4 and are now on the Z06, seventh season of autox, avg about 20 events a year & swap between 4 sets of rims/tires & same lug nuts. I gun them off & back on (easy). Finish with tq wrench. The threads are probably a bit over dimension now, but they keep the wheels on over 1g turns on A6 tires.

For high speed (track) I'd be tossing them by now, but low speed (autox say 80 - 90) they are still getting the job done.

I just last week ordered the ones I posted about earlier in the thread with the threaded shank.

A few more threads of engagement can't hurt.

Same here; I've been using the same set since '02 when we bought the car with no problems. If anything the aluminum flange/face (whatever you call the angled seat) on the wheels will see more wear.

Have a good one,

I've only seen lugs and studs damaged by overtorquing or cross-threading.

Jason

Every time I put the car on jacks, I put my lugnuts in a bowl and spray them down with WD40. Seems to help prevent cross threading.

Z06Fix

I run mine off and on with a gun then finsh with a tq wrech as well. They are not rounding bad by any means but the socket is just a touch loose on them. I would love to have something that fits perfect and will take the abuse of an impact.

I have always added a touch of antiseize to the threads 2-3 times a season. Never had an issue with cross threading.

froggy47

I might wonder if you have a good fit between the nut & socket? I guess they do vary a mm or so from brand to brand.

Well at least they are cheap enough to toss & replace.

On my way out now to pull the wheels of my Z, corded the rears yesterday. I'll throw the street set on till the next event 2/15. My tire guy is on speed dial.





Be safe guys.

PS: I use anti seize also & torque to 95 rather than 100.

I found that removing torqued lugnuts with my rattlegun seemed to be hard on the threads. After changing out a boogered up front stud (thanks Jason for the tools and spare stud) at the track one time, I've stopped removing lugs that way. I now go around with a breaker bar and "un-torque" them all and then follow with the impact once they're loose. Takes only a few seconds longer and seems to keep the studs/lugs happier.

I got a full season out of this set of studs (GM Extended) and nuts (GM OEM open) with no issues. We typically remove and install tires at least 6 times during a normal weekend, so that's quite a bit of usage.

I'm changing everything out with ARP parts this year as preventative maintenance anyway.

YMMV

I know longer racing studs are preferred, but what's the benefit of running an open end lug nut on the factory GM studs?

VetteDrmr

It's not related to open/closed ended lugs, but all of the peanut/closed end lugs that I've come across are chrome-plated, which are the only lugnuts I've had problems with galling/breaking threads, which usually ends up killing the stud also.

Other than that I think they'd be the same as any other lug.

Have a good one,
Mike

Jason

The fake chrome covers don't take well to impact guns. The closed end can get packed full of crud and prevent the nut from seating.

froggy47

Also, there is the chance of a mis match in length between a lug & a closed lug nut. You torque it to spec & you think all is good, but you have really torqued the closed nut to bottom out & the wheel is loose on the hub.

Not probably but s##t happens, especially if a car has had more than one owner.

blackvetterzo6

I just ordered a torque stick. This seems to be pretty cool. They make them at all different torques and sizes. Hits 100ft lbs it breaks loose and your good to go.For the track i would think this would be great.

The amount of thread engagement can be inspected by eye. (Plus the
other things people mentioned).

And they're lighter
