Default Kyokugen lug nuts?

How much does a set of 20 weigh on one's wheels compared to the standard ones?

What is the weight savings? Is it significant enough to warrant it's purchase?


I think I like them but I've also heard bad stories about people stripping the wheel hub studs too...

Any feedback appreciated.

I wouldn't get them. All the ones I've seen have had issues.

The issue is not the key. It is the lugs. Kyokogen makes the key so that it will break a few pound-feet before the lugs break. They didn't make the key weak because of some oversight or lame engineering. They did this on purpose.

It is easier to replace a broken key than to remove a stripped lug. So the weakness of the key is an indication of the weakness of the lugs.

i get emails/phone calls calling about these lugs all the time... and they always seem to strip at the most critical time --- when you need 'em --- ( i guess that's murphy's law at work )...

save yourself the trouble!

good luck!

i'm currectly in the broken key situation, and i as soon as i have the bastage mechanic who used an impact gun when told explicitly NOT TO, i plan to continue using them.

The lugs are more than adequate, and i beleive my key cracked at over 140 ft-lbs. cosidering i torque lugs personally to just under 90, i think the setupis fine for people who understand how tight they need wheel lugs to be.

90 is overdoing it boxologist! at least according to the WRX owners manual its supposed to be in the range of 57-72.

are there any other good light weight lug nut sets out there that don't have the issue of braking keys, etc.?

anyways, how much weight reduction is gained with lug nuts? what do stock nuts weigh compared to a set of lightweight ones?

for the tuner spline drive lugs compared to say the durarlim lugs you save approx 1 lbs per wheel

The way I see it is that if I torque to each lug to 75 ft-lbs., there is 375 ft-lbs holding each wheel on.....which is more than enough...and which will prevent most, if not all, problems associated with the 'gorilla torque on the lugs' syndrome that so many seem to experience.

Ok....some people seem to think that they have to severly overtorque their lugs and have problems with stripped/broken studs and broken keys.
Simple.
Putting 90+ ft-lbs. on lugs is severly overtorquing them....which = problems....hell, putting over 80 ft-lbs. is too much unless you race.
Don't overtorque your lugs, and if you use alloy lugs, then having some 'gorilla' at a shop overtorque them is your problem because you allowed it to happen. Don't do it, and don't allow it.
Simple.

So are the spline drive lugs you sell Kyokugen lugs?

Thanks,

I have used McGard splinedrives for about a year now, with probably around 40 wheel changes, and I couldn't be happier. No problems at all, and they even have most of the (black) color left. One additional nice feature that I haven't seen with other lugnuts is that they have a rotating seat, so that they don't strip the paint/finish of the wheel as much when you tighten them. They're kind of pricey, but worth it. www.oakos.com is a good source.

If anybody has problems removing Kyokugen lugs after stripping the tool, I posted detailed instructions in an older thread. You should be able to find it with a search.

I don't mind the lugnuts, it's the tool that sucks which many have said. I use the Zenki ones now, they work well as long as you don't use an impact on them. If you use an impact enough on them it'll strip the threads out on the lugnut, and generally leave them stuck onto the stud.

Ack...please save yourself the trouble of buying these. I had my car on jackstands when my key broke and was stuck for 2 days finding a shop that would sell me the key. Although it was due to the lugs being overtorqued by the last shop that threw tires on my car, it seems to be a major problem with this brand.

I know I'm resurrecting an old thread, but I registered just to ask one question. Where can I buy replacement key for the kyokyugen lug nuts? Mine broke when an uninformed mechanic used an airgun. I borrowed a friend's, but that one was already broken even before I used it. It looks like i need a third key.

Talk to the store where you got your lugnuts from. If they cannot help you, then try talking to another retailer that carries Kyokyugen products.
