Push, Very impressive sir. What do you do with such a long stud?
(sorry...the question had to be asked...)
3" long studs is typical of US race cars, the reason being they use long lug nuts.
As long as I can remember it has been that way. I first noticed these on the late 60s "Trans Am" road race cars.
You will see them in vintage pictures of the Shelby Racing Co Boss 302's with the Minilite wheels.
Here is a picture of a lug nut from a Mustang that was raced.
This one was purchased from "American Racing Wheels" around 1972 and was used on my 200s wheels. It's 1/2"-20 thread.
The greater length gives you greater load capacity, it reduces the bending on the stud AND last but not least, they are easier to hold and start on the studs.
The ends are also open so you can see how far the stud is in the lug.
The standard length studs were notorious for snapping even just torking up the wheels.
