OEM lug nuts the lightest?
 

So I've been looking into lug nuts, and based on this photo:

...the OEM lug nuts are the lightest I've found so far. Although I admit I kind of stopped looking once I realized they might be lighter than Rays. I'm suspecting maybe that scale is just not precise or accurate at such small weights?

That just doesn't seem right. Maybe I screwed up the math? @JRitt?

use grams for lug nuts

yes, that scale doesn't look like it would be accurate for such a small size

also race application lugs are usually larger/longer for reasons of utility and strength

Yeah, that makes more sense. I'll convert them later, but still, the numbers will still convert to lower numbers for OEM vs. the others.

Once I get home (only 2 more months to go!!!) I'll be happy to weigh the stockers on a smaller scale and in grams. But until then, if someone wants to be heroic...

I weighed mine on a decent small scale and apart from the really light aluminum ones they are lighter. The OEM lugnuts don't weigh much at all. The issue for me is the lug seat area on them isn't very long so if you are using aftermarket rims you probably don't want to use them. But for OEM rims I wouldn't bother with anything else unless you want to switch colors, are using longer studs, etc.

Shameless plug. CSG aluminum lugnuts are tested through rally and track conditions. A set of 20 lugs weighed in at 13 ounces (368.5 grams), or approximately 0.04 lbs (18.4 grams) per lug nut. Weight was done by third party individual: @Captain Insano. :thumbup:

We have some ultra heavy duty lug nuts made from chromoly steel coming in for the guys who want to absolutely thrash their lug nuts to hell. They are 0.11lbs (49.9 grams) each. A sample of lug nuts were salt fog/environmentally tested to test the durability of the rust-resistant coating as well with certificate. :)

OEM lug nuts suck. The internal threads seem to be soft and easy to damage. They definitely do not hold up well to regular mounting and dismounting, even if handled with care.

Personally, I don't think there is much "speed" to be found in lug nuts alone, unless you are in a racing class that allows for a huge range of mods. I look for reliability and convenience of use.

I wanted a cheap fix and picked up a set of these steel ones a while back and they are great! Just long enough that they are easy to handle and thread on by hand and being steel, there is no worries that they will stretch with heat.

They use a 17mm, so being slightly narrower than stock (19mm) is good if you have have any clearance issues with your aftermarket rims.

How often have you guys had to retorque them between sessions? I've always avoided aluminum due to stories of them backing out or coming loose due to different thermal expansion rates w/ steel lug bolts.

Haven't had to retorque any of the lugs. :)

Gorilla forged aluminum are lighter than stock. Please refer to my wheel thread.

Thanks for the info, guys. Updated my post: http://www.ft86club.com/forums/showp...&postcount=147

I dug up my OEM 2013 Subaru BRZ lugnuts and weighed them for you.

1 lugnut = 25 g (actual measurement)
5 lugnuts = 125 g (4.40925 oz., or 0.27558 lbs.) (actual measurement)
10 lugnuts = 250 g (actual measurement)

I weighed them on an accurate scale that measures in 1 g increments. I then measured 100 U.S. pennies as a reference check, and found it accurately measured 250 g, as it should. So, I think you can trust this measurement. Note that the lugnuts were not scrubbed clean and a 0.1 g scale would measure a bit of brake dust adhering to these dirty lugnuts. I hope this degree of accuracy is sufficient for your needs. :)

Stay safe.

And, thank you for your service.

Nice! And 125g is only .3 grams off of what I already had listed, so it's good to know peoples' scales are reading so close. I'll use this as an additional reference.
