Hey guys, I want to upgrade my wheel studs to ARP's. I am paranoid about one breaking due to the power (had some prior bad experiences). Anyways I have a 93 5.0 with the 17x9 Cobra rims. I assume these are the proper studs to get .... http://www.americanmuscle.com/arp-re...tuds-9404.html , but what my real question is which lug nuts to use? I know open ended ones are probably required, but which ones work? Which ones have the proper angle? What angle is required 60 or 90? Thanks for your help in advance!

I don't know 100% but I'll bet they are 1/2x20 thread.
Buy the studs and then the open lugs local is what I'd do.....

I know the specs of the stud, but what I really want to know is what the proper angle on the lug nut needs to be. I have a 06 cobalt and I broke 8 wheel studs because I had aftermarket rims and the wrong angle on my lug nuts. I put ARP studs on there with the proper angle lug nuts and I have not had a problem since. I DO NOT want the same thing to happen with this car. Thats what I am really asking.

The angel of the lug nut is determined by the rims you have. Are the rims factory ford rims?
The rims on my car are 17x8 factory ford cobra rims. If you have cobra replicas you need to go by the manufactures recommendations for the proper lug nuts.

Mine are the Cobra R rims (probably replicas).
