I pulled my rotors off today to repack the bearings and I saw that two studs have been replaced on the pass. side. Although I never had a problem I think it is a good time to replace all the factory studs with longer ARP ones.

Should I use 1/2" or 12mm?
Press in or screw in?
What length?
Open or closed lug nut?

The rear is already done with Moser 3" long 5/8" studs.

Could someone point me in the right direction?

 

Well... I ordered from Summit Racing today. I hope I got the right ones. I ordered ARP-100-7708. I think they are one inch longer than the factory ones.

 

Those are right; 2.5" long.

GM 22551491 is 2.9x" long but I don't know if that's thread length or total (there's a bit at the end that's unthreaded)

 

jmd, you told me to buy .769" long shank the other day. I havn't tried them yet, since im not near my car, but I hope they fit.

edit.. yeah.. it said studs. Didn't catch that. I thought it said lug nuts. Well it did but thats not what he was talkin about.

Sorry bout that

 

Hey red, what is the shank legth on your lug nuts? It doesnt matter if its with or without the washer.

thanks

 

I'm glad I bought the right ones.

lug nuts are 1 1/8" long measured with out washer. Wheels are 1 3/8" thick.

 

Do the center caps for your wheels have a blue center that says weld racing?

 

I can't remember the color for sure, but they are genuine Weld wheels.
