i see so many people spending over 100 dollars to get lighter lugnuts..maybe a few ounces over stock...wats the point? All of them might add up to taking a few pounds off..but is it so significant to spend all that cash? I know your taking weight off the most important part of the car (the wheels; lower part) but a few pounds isn't gonna help that much correct? Am i missing sumtin here?

 

It's not important because their lower, it's important because it's rotating mass, not just dead weight...Something you'd have to get from a physics class, I'm too tired to explain...As for importance, it sure as heck isn't important for the daily driven weekend fun car, chances are you wouldn't notice a difference at all...for all out road race or drag or whatever, every pound counts, especially rotating mass.

You won't notice a difference since it's so close to the hub.

Well said.

 

it's not just rotating mass either, it's unsprung weight as well.

 

yeah, 2lbs out of 2000 probably is noticable, by NO ONE...getting a haircut probably affects unsprung weight by about the same amount...

My hair is sprung, and if you've got 2000 lb of unsprung mass, you're in trouble. That said, people buying light lugnuts had better make damned sure they're strong. I've seen a wheel come off at an autocross, and it's not a pretty sight.

 

its makes you faster...you didnt know that.....hahah

 

of course it wont be noticed.... but the fact is that every ounce adds up...

 

Three words:

Less rotational mass

Works on the same theory as why cars with heavy *** 20" chrome wheels are slower than the same with the stock wheels.

 

the lighter the car and less mass on the wheels the faster your Honda will be. It also has to do with inertia...........

you have unsprung, and sprung weight confused.

 

I got them because

Yeah in theory, but rotational mass makes more of a difference the further away from the center of rotation it is.

Huge rims not only are much heavier, the weight is much further out from the center so its even worse.

Two pounds less at the edge of the rim is going to make much more of a difference than two pounds right at the hub.

 

But we're talking a few ounces a wheel here....an inch or so from the very center. The ONLY people that should be buying these are pro race car drivers (Drag or race or scca, etc.) If you're a weekend warrior and you bought these, punch yourself in the *****.....twice. If you don't even race except maybe your weekend drag from the stop light against your fellow ricer friend driving the cavalier with altezzas and you bought these....follow the ball punching with a swift kick to your own ***. LOL, give me a break. Some people make me laugh so hard. Ughhhh...dude, I could spend an extra 100 bucks on some lighter lugnuts and that will make me really cool, awesome lets do it.

BAH - to all the ricers.

it helps acceleration and braking.. little stuff adds up

 

Maybe this will simplify things for some people...

Think of a wheel as a huge lever. More weight towards the outside will make it harder to turn the lever. This is why a lighter wheel may not be the best choice...it depends on where the weight is. Since the lug nuts are essentially at the very center of the wheel, that negates the whole moment-of-inertia argument.

Not necissarily true, since you would have more leverage. Which is why it is benificial to have a very heavy shift ****, you have more leverage. The shift linkage essentially works like a lever.

If you look at the weight of a stock lug nut, vs the weight of a spoon lug nut and add up all four I think you save 1-2lbs total. (did the math awhile back).

 

1 pound of rotational mass=10 pounds of static mass on a car

 

how did you figure 1 pound of rotational mass = 10 lbs of static mass? This math is VERY flawed because it can vary so much depending on how far this weight is from the center. Here is an example.if you have 18" 12 lb wheel compared to 14" 13lb wheel...guess what? The smaller but heavier wheel is actually going to seem to weigh less to the engine.

As far as the reference to the lever above....I think maybe he meant something along the lines of if you have a 10 lb stick that is 20 ft long and you hold it in the middle and try to rotate it, its going to be much harder to do so compared to a 10 lb stick that is only a foot long.

I can't believe people are actually giving a thumbs up to spending a **** ton of money on some "lightweight" lug nuts. Maybe .5% of the people on this board really could see the benefits of these. As in people with REAL drag/track cars.

People come up with these stupid little equations that have no real world validity.

The fact is, yes, it's less rotational mass for more horsepower to the wheels (though you are not going to notice the difference.. And better braking, again, you won't notice the difference. And it's less unsprung weight for better handling, and a smoother ride, but once again, you won't notice the difference.

They are not worth the money, even for a race car. They are really only useful for the bling factor, if you like that sort of thing.

It was in a little publication a few years ago,, perhaps you have read it,, its called Hot Rod Magazine

Actuailly most people run them because they have to get open ended lug nuts to pass a tech inspection. The light weight ones cost the same as regular ones, so why not go lighter?
