redsx13= why did you lose a wheel from extended lugs? you can't just post pictures of your messed up car and blame them without any proof. Drag cars run extended studs ALL DAY with no problem.

Before you go spouting off uneducated shit. Do you drive a drag car? there is a reason they run extended studs, and they damn sure are not worried about wheel fitment. It's a safety measure why drag cars run extended studs.

equivalent to or greater than the diameter of the stud. Length of the
stud does not determine permissibility; length of the engagement
between the stud and lug determines permissibility. See General
Regulations 5:2.
EX: So what that pretty much means if the diameter of the stud is 1/2" it must stick out past the lug by 1/2".

The reason why BOLT ON spacers (hub-centric if possible) are better than just throwing a huge spacer over extended wheel studs. Is the spacer is designed to take the tq transfer of the car as if it were an extension of the hub itself. There is no wiggle room for it to rotate.
I explained why just putting a slide on spacer were no bueno on extended wheel studs. They freely rotate within the limits of the wheel studs, and if their stress rating is being exceeded by rotating mass, they will simply bend or snap off.
