do you need open lug nuts for the 150 club??
I was told last year that I had to have them if I wanted to race in the 150 club, when we
were do the 130 club.
But in the rules it doesn't say nothing about open lug nuts and the tech sheet doesn't specify

If I do need some open lug nuts what are good ones to go with for the car.
I have an 82 chevy Camaro and the lug nuts i have are closed end or acorn.
the studs are 12mm x 1.50.
Would I also need 1/2 studs and 1 inch lug nuts if I plan on going faster the 150 mph in the future???
Thanks for your help,

You might address your question to or come to the USFRA club meeting 7 pm first Wed. of every month upstairs at Totems on Redwood rd.

I don't know if you got your question answered yet, but I am pretty sure that is something they checked on our car last year, and we were in 150.

If they told you that you would need open lug nuts in inspection last year I would guess that you need open lug nuts. For over 150 the rule starting on page 19 spells it out. (2.G) Will they let you slide with a 12mm stud? Ask in inspection this year. What is your tire diameter? I think you can buy the lug nuts you want from Joe Panak at Roto-Faze

The OEM lugnuts on that Camaro are open nuts with a tin cover.
You can remove the tin cover if you don't want to buy new nuts.
When I ran the 150 club they never said anything about open nuts.
I would give them a call to make sure.

rule of thumb  150 almost has to pass SCTA race car saftey rules--lug nuts would apply in my opinion

My son and I ran (and both made it) in the 150 Club last year in his nearly stock, daily driver 350Z that we drove to the Salt.   We ran the stock, closed end lug nuts.  I don't remember the inspectors showing much interest in them in tech, but I suppose you could always pull one to show 'em you've got adequate thread.   They're not mentioned in the 150 Club rules on their web site, either. 

We just did the stuff listed on the rules as per the website, and didn't really have much problem.  One inspector was talking about leg restraints (full door opening net), but we had a copy of the rules with us, it wasn't listed as a requirement, and we prevailed.   The inspectors rightly have the final say on these things, and should err on the side of safety, but if it isn't listed in the rules...

Anyway, you can always call the number on their website, and Ellen will hook you up with an inspector.

Lug nuts with shoulders are required in case you get sideways and a wheel pulls over stock lug nuts.  There's some bad experience behind every rule on the salt.
