I'm pretty sure I have the same ones pictured multiple times earlier too. They were on the car when I received it, presumably installed by the dealer. Seems to be some kind of standard-issue Nissan locking lug thing. I haven't had any issues yet, but I'd rather not have any in the future.

I hadn't thought about the fact that these don't have washers like the other lugs. Is this really an issue? Should I get them off the car?

Yes. If you are using a locking lug that does not match the non-locking lug nuts, and one without a washer when the others have one, then the washerless locking lug is not seating on the rim properly; this affects torque values on the studs and hub, plus can damage your rim. If your dealer installed them, have your dealer replace them with the proper locking lugs.

Yes - don't even waste time with them. Replace them with stockers and tell the dealership that you want a new set when ones specifically for the 370Z come out. They seriously are crap.

Yeah. CRAP! I should get a refund for the price of those stupid lugs. The absolute WORST thing about this whole debacle is that the proper lugs are available.

We should sticky something about this and change the title so that new owners see it, this is going to be an issue for a *lot* of people I bet.

I just got back from visiting the service manager at my dealer. I gave him the rundown about the broken wheel stud report here, and the differing locking nut part numbers available from Nissan. Sure enough, they've been putting the wrong lock nuts on all of their 370's, not just mine. He had three more on the showroom floor already equipped with the wrong ones. He's ordering a bunch of replacements for all his stock and for my car (and hopefully for anyone else that has purchased in the meantime, I didn't ask or think to until I got home).

He gave me some plain wheel nuts (of the correct type) to put on my car for now and offered to install them himself, but I said I'd do it when I got home.

He says Nissan never notified them about the availability (much less *requirement* apparently) of different lock nuts for the 370Z's wheels. They had never heard of the part before I walked in and told them to look it up. They've been using the same "standard" locknuts they use on every car. I think it's fair to assume a lot of dealers are going to be in the same clueless boat about this.

Speaking of clueless, you guys realize this all has been covered already in this thread, right? Wheels Locks

I warned everyone in that thread not to use Nissan's standard wheel locks, and supplied the McGard part number for the shank-style locks that do work (this was before Nissan caught up and started selling them under their own name). I've had them on my Z since January without issue.

add me to the list of those 370Z's with the wrong wheel locks installed by the dealer. Read this thread, checked mine and unfortunately they are the tapered locks, the wrong ones. Fortunately, no harm no foul, I re-installed the stock lugs that they conveniently left me in the glove box. The locking lugs the dealer installed couldn't have been torqued to anything greater than 20#'s, they were just above finger tight. No idea what the dealership is/was thinking, are these guys clueless?

Thanks guys, for bringing this to light.

They can't be torqued correctly because they are the wrong ones. Glad you were able to remove them and didn't try and tighten them.

You know, this just scares me. I mean, some dealer tech puts on wheel lock and can't torque it down properly. Shouldn't that raise a red flag? Wouldn't the common sense next step be to remove the wheel lock and stick a regular lug nut on it? But noooo...what happens? The tech just leaves it on, barely tighter than finger-tight. Is negligence just a way of life for some people?

Well it seems like they are torqued correctly but what actually is happening is that the stud bottoms out in the nut before the taper makes full contact with the wheel. So it will seem tight at the time but within just a few miles they will start backing off. Mine were only on there for about 40 miles and had backed down from 80 ft/lbs to probably 50 ft/lbs, I can only imagine with a few more miles they would have gone finger tight and eventually probably fell off on their own.

Ah, I see. Makes sense. Okay, my faith in humanity is restored. Partially, at least.

So today I heard a hissing sound from the passenger rear tire. I go around to check and there is a piece of metal sticking in my tire. When I put the spare on the wheel lock BROKE, yes it BROKE!

So I managed to go to Discount Tire during rush hour. I was told the tire could not be repaired. The technician said, "Wow these tires are expensive, $325 a piece! Unfortunately there aren't any in the state of Texas!" He said I should go to Nissan and try to get them to give me another tire since the car is still new. Ok... I already know Nissan isn't going to give me a new tire, but I live in the 4th largest city in the US and a huge tire company doesn't have the size for my car.

IF YOUR CAR CAME WITH WHEEL LOCKS ON TAKE THEM OFF AND GET THE RIGHT ONES!

Tomorrow I have to take off work to take care of this and I can guarantee you Nissan will not have the tire in stock nor will they have the CORRECT wheel locks. I've dealt with Nissan long enough to know this.

Fortunately they were able to remove the broken wheel lock. By the way the wheel lock felt like a piece of plastic.

I hate and I mean HATE driving with a spare! Oh well... I'll let you know what the A$$holes say at Nissan.

wow.. I'm very sorry to hear this. My dealer installed a set of wheel locks FREE as a courtesy. I'm going to take them off ASAP. Where's the link to Mcguards part?
