Bad Karma

I'm in the process of figuring sorting out 18" wheels up front (make more room for my Wilwoods and maybe make the jump to 14" rotors next replacement).

So, I'm looking at TSW Nurburgring wheels, which everybody tries to sell with the keyed lug nuts. Do I have to buy them in order to use these wheels? I'd be fine reusing my stockers if I can and when I replace the hubs (or fab my spindle ducts) I'll upgrade the wheel studs to a set of longer ARP studs, which I'm thinking might be too long to use those lug nuts.

Anybody know for sure what works?

You want to use open lug nuts.

That's what I was thinking. Is there room in the Nurburgring for a normal socket to reuse factory lugs?

Your stockers will work fine.

Yes, normal sockets fit fine, and there's just barely enough room to use some impact sockets.

I assume you are going to track/autox.

Some/most sanctioning bodies will require a tech inspection. If you have (stock) closed end lug nuts, they may fail you or may require that you remove a nut to check that you have sufficient thread engagement.

Some tech inspectors are pretty **** in my experience, looking for any little thing to make you "jump thru a hoop" to get the car on track.

The ones who have been doing it longer, tend to have more common sense to use.

Open lug nuts eliminate this issue.

Gorilla makes a thin-walled impact socket in 19mm and it's available thru Amazon. I use one for my AFS ZR-1 style wheels and it easily clears the recessed area. I use stock GM lugnuts.

Our association's autocross rules for lugnuts and studs require a minimum of 9 turns of the lugnut before tightening. For OEM wheels and studs, that works.

I'm not familiar with the specific wheel, but I would make sure that if you are using stock lugnuts, the wheel uses a lugnut with a 60 degree conical tapered seat (stock GM).

Yeah definitely going out on track. I'll have to go shopping for a thin walled socket for em.

you don't need an "impact" socket for your wheels, shouldn't be torquing them with an impact guy anyway (just spin them down lightly). I use a thin-walled 1/2" socket, fits most any wheel, not an actual impact socket

froggy47

You can use a thin wall std socket with the gun, just spin it easy like David says, don't HAMMER IT.

Bad Karma

Yeah, I never beat it down with the gun. Impact on then final torque with a torque wrench to 100 ft-lbs.

Froggy,

Where can you find open lug nuts for a C6?

I have seen the Pfadt lug nuts but those are fugly yellow.

NAPA, Amazon, ebay,

Open end nuts and only use the impact gun for removal. Here's why.
