Has any1 had any issues regarding durability of the stock premium chrome five spoke GM stamped rims at track?

Also does anyone know where to get more hardened lug nuts than the ones they carry at the dealer for $4.25 ea.for these stock rims. They suck IMO replaced a few already,they're kinda soft metal for lugs.I'd swear they tighten themselves or sieze up,I torque'em and later aaarghh

 

Don't know which wheel you are asking about. The five spoke Z28 wheels are not "stamped"; they are cast. If you are talking about the stock Camaro stamped steel wheels, they should last forever. That is why NASCAR still requires stamped steel wheels.

I've done some racing on the white spoke 4th gen stock wheels, have done some hot lapping on my stock chrome spokers with my 4th gen too. No problems, that is what the CMC 4th gen racers use too. I use the stock lug nuts, haven't had any problems from them. If I remember right the stock torque spec is 100ft-lbs, is that what you are using? On my third gen I run the GTA wheels and use 85ft-lbs. More than 95ft-lbs on those wheels damages them (as I found out )

 

Only thing I can think of, is why race on chrome? The 3rd gen had access to the lightest wheels (GTA Enkei style), but at least you can shave a little by going to a regular old 16x8" wheel instead of chromed.

I haven't heard of any breaking, as for the 17 inchers, there are a couple stories.

 

Lateapex sorry for the confusion the stock rims are 16x9 chrome five spoke premium option and have a GM stamped into them,you know as a brand kinda stamp. Doc They came with the car,they're on both my cars...guess I could look into lighter wheels later.
Lady in nomex,I've been torqueing them to 95lbs. only I better go anther 5lbs.This was what I was told to torque them to by a tire guy geez.you think thats whats causing the lugs to tighten/sieze not enough torque in the begining?Not all lugs all the time but yes I've had to replace quite a few after struggling to get them off and ruining the lug.So bad at times I break sockets,round off nuts etc.

I sill would like to get some hardened lugs that are better quality steel then the stockers,the guy at the dealer says"thats all there is"

 

The only care I've evern broken a lug off of, was an 88 MR2, and it was because someone put them on apperantly with air tools and did NOT thread it by hand first

It was not my car, but I still find such workmanship very, very upsetting. That is why other people dont touch my car, except for a particular alignment shop, and I will be doing that myself now as well (not because of this shop! A+ work).

If you've taken your tires in to be done, I would suspect that probably, if you can verify to yourself that it has been a problem after.

For me, the lugs were very very sticky, so I knew right off the bat something was wrong. I'm not a really small guy either, so I knew it was completely unreasonable how stuck they were, sure enough it just got harder and harder to get them progressing further. About at the half way point, with several moderate breaks in between turning, the lugs were still heating up from all the friction of twisting, and I ended up breaking one completely off, oops.

People at generic tire shops with air tools dont even seem to thread them on by hand, just put it in the tool and off they go, very bad. Plus if a stud is torqued all at once, one at a time intead of in a pattern, it will not be good for the studs either. There are ARP studs that you could use, but stock still work fine for me (?)

 

I change my wheels when I autocross every month. I use a quality torque wrench set at 85 pounds. I also tighten themALL down by hand before torquing them for the final time. I've never had a problem so far on factory aluminum wheels and stock lugs. I also put just a little grease on the threads when I first get a car. Just be careful not to get any on the surface of the lug nut where it meets the wheel. You need that contact to be clean so they stay tight. But I've found that just a hint of grease on the treads keeps them from rusting and helps them come off without heating up.
