ok so its gotten to the point to where im doing the whole weight reduction thing with my s2k, and i had just bought the NRG black chrome alunimum lug nuts was suprised how light they were however when installing them somehow 2 lugs striped the thread right out of the lug, the thread was right 1.5 and i was hand tightening them and im like wtf? im suppose to trust my rims to be held on by these things? so i talked with nrg and dont dont know wtf so im goin with a different company, i was looking at the blox black chrome lugs here :http://www.weaksauceparts.com/store/...at=2152&page=1
however i noticed that these were alumnnim as well, has anyone used blox lug nuts? are they cheaply made like the nrg ones or are they really well made and i wont strip it?
or should i go with the Forged blox lug nuts? here : http://www.advancespeedshop.com/blox-racin...04-p-11572.html

 

2hp? thats mad horsepower dawg XD but thanks for your 2 sense i just heard that rotational weight tends to add up more to weight reduction then normal body weight lose

 

Lug nuts, being close in to the center of the wheel, contribute about zero percent to combined wheel/brake disk/tire rotational inertia.

You would never be able to measure the difference between standard steel lug nuts and even magical zero-mass lug nuts at the dyno, drag strip, autoX, or road course.

 

GET A TORQUE WRENCH!! 12mm X 1.5 steel lug nuts should be torqued to 80 ft/lb. I am not sure what aluminum should be.

The idea here would be unsprung weight, not rotational inertia. Many people claim that each pound of reduction of unsprung weight is equal to four pounds of weight reduction on the body.

On the MR2, we lost a pound off each wheel just by changing the massive OEM nuts to the most basic open steel nut. We also exchanged those 19 lb wheels for Volks that weighed 8 1/2 lb front and 9 1/2 rear. That gained us about a half second for an autocross run.

Aluminum racing nuts are intended to be a one time use item - new nuts every time you take the wheels off. Spend the bucks for titanium if want light weight and a little more security.

 

Yes. I'm surprised many people spend alot of money on all sorts of parts but do not consider getting proper tools to get the parts fitted.

Even the best lug nuts (IE - Rays) will strip and are prone to severe damage when overtorqued by "feel" or rattle guns.
