C7 Race Star lug nuts
I ordered Mcgard 63004 lug nuts and the shank is too narrow at .679. The washers are too small as well. Am I supposed to be using .740 shank nuts? Yes, I need 1/2-20. These are c7 wheels on a non corvette. (although I do own a corvette as well.)
Would Mcgard 62820 be what I need?
Thanks.
