Ive heard that the fact that the lightweight lugnuts are made of aluminum or magnesium - makes them start reacting with the different kind of metal threads (steel? iron?) and possibly get stuck because of chemical reaction!!!!!

As I did take a bit of some chemistry, and a little bit of knowledge is a dangerous thing.., I see this as a very possible and negative outcome of going for this kind of weight reduction. I dont want to screw up my car.

Does anyone know about this or other problems with lightweight lugnuts?

I cant help but think that the high heat of track running make any possible electrolysis reactions go faster. It just seems like a bad way to spend $ 70-80 bucks for minor weight reduction given what might happen- (have also heard that they arent that sturdy) - plus it is weight reduction that is very close to the center of the wheel anyways and that lessens it's effect.

Comments from the board?

See I was thinking of getting these for a little rotational weight reduction but now your giving me second thoughts.

Maybe if they show sings of cold welding you can use some anti-seeze lube on the wheel studs.

 

I know i guy uses them on a 800hp race car that weighs 2300lbs (a dirt car) he's had his axels and wheels bendfrom getting hit but nuts have never broken. And goes through a set of tires every time they race and the aluminum lugnuts come on and of everytime with a very big impact gun.

There anodized maybe that helps but i stoped worrying after i talked to him .But i will prob use some lube when my little buddies go on

 

You save a few OUNCES of rotating weight by using them, and it's at the center of the wheel. Honestly, the only time tou need stuff like that is if you're driving an F1 car. otherwise just leave the stockers on.
want to lose rotating weight? shave your tires or buy lighter wheels. you'll save a LOT more weight than with those lugnuts, and you won't have to worry about the rest of those issues.

 

I've seen 2-3lbs lost from outer tireweight from shaving and/or normal wear.

 

Agreed. Not worth it.
