Just got some new American Racing Ansen Sprint rims. Need new lug nuts because mine are too long. What lug nuts are you supposed to use on these? Had Shelby Cal 500's previously.

that should help, an interesting thing about this forumis you see relevant threads below yours, course you dont see them till your thread is created, but yeah here it is.

 

The other thread is very confusing and doesn't really answer my question.
I've done some further research and some people tell me conical, some shank. These are new ansen sprints going on stock studs. I need to know what type of lug nuts. its 1" stud length, 7/16" diameter. I'm kinda screwed here.

 

Did you contact these guys?

Or the OP (smcurro) from the other thread to get dimensions on the ones he got?

 

Quick google search provided info from Summit that those would have 60 degree conical seats. Atleast when i ordered my keystones from them, i ordered bolts purely from their ( summits) information and got the right ones.

Then just look for a set of 7/16 20 RH - nuts. I used Gorilla Automotive for lock nuts.
You should also measure are your nuts intented to go "inside the rim face" like on Keystones- which i think is pretty unique solution tho.

Otherwise, dropping a mail to manufacturer would give you an dead-sure answer for what bolts to use if you dont want to pull the trigger.
