i recently purchased a nice used set of torque thrust wheels from a HHR. I am trying to figure out the correct lug nut to use. Any help would be appreciated

 

What is a torque thrust wheel? What would be the difference in lug nuts?

I don't know.

 

They are made by American racing wheel . I have seen other members on threads discussing them but could not find info. On the recommendation for lug nut style.
Lug nuts can be acorn style with a concave mount, a concave style with washer, or flat mount with washer. The flat style with washer can come in different lengths so they are concentric to the hole opening in the wheel.

 

Have you tried http://www.americanracing.com/ ? They sell the nuts, I assume they would be able to match them up.

 

Many times you can tell by the hole the stud comes through. If it's a round hole with an acorn style seat, then acorn style lugs. If it's oval or flat, then it should be the washer style. For length, you'll have to measure.
