how much does the stock 17" rim weight? I've been searching the web for this spec but no luck so far. =T Did searches here as well, but no luck yet.

 

wheel with tire - 42lbs, tire is around 22-23, so the rim is around 19lbs.

 

The lug nuts are fairly substanial in weight too.

 

oh really? anybody have any real weight data about this? the oem wheels with lugs, that is.

 

You gotta be kidding me... First time I hear somebody trying to take into account lug nut weight for a street car... The lug nuts are so close to rotational axis that their weight is not going to make significant difference.

In any case - 5 lug nuts - what 1lb?

 

In my street car, I could not care less about lug nut weight. On a track car, however, yes, it will make a difference, if only slight. If you think replacing lug nuts for weight savings is insane, how about replacing wheel studs? http://www.mettec.com/latemodel.htm hahaha. This only makes a difference for the no A/C, no sound deadening, no interior, "got to take a crap before I race crowd."

I am not sure, as I don't have a scale handy. However, when I put on snow tires, I recevied open ended lug nuts to properly mount the tires. They were, I estimate, half the weight of the stock lug nuts.

 

I have light weight Kyokugen open ended lug nuts on my 240sx. The packaging says that they weigh 25g per nut. The whole pack of 20 nuts weighs just over a pound!

 

Have you had any problems with them?

 

I haven't run them yet on my car. I'm waiting on additional parts so that I can swap everything at the same time (spindles, hubs, wheels). I hear that you need to be careful with them, though. 60ft-lbs of torque, anti-seize on the threads, and absoltely no impact wrenches are what have been recommended to me by friends. They cost me $45 on eBay. I had to buy lug nuts anyways, so might as well spend a few extra bucks on some nice ones! They're also 7-sided for built in safety (yes, you get a special socket).
