This thread got me thinking...

If I'm mainly street, with some strip time, which studs do you go with so you have a stock look on the street (closed acorn lug nuts), but meet racing requirements for the strip (open hex)? (And say I may want the option to throw on some different wheels/tires for racing.) Are the pressed in stock type ok, or are longer screw-in type a must? In other words, which choice to get the best of both worlds?

This would be 400HP range, in a light a-body I'd expect easy 12's in the 1/4 with decent hook up. And keeping typical 10x2.5 drums on the rear.

You use a stud that will be enough to hold your wheel on, so if you use a stl wheel you need a normal stud and a conical/tapered/acorn style nut.
If you use a AL wheel then you may need a flat style nut or even a conical/tapered/acorn style or a ball radius style on AL wheels also.

There are only 3 types of nuts and lug bolt styles which are 1. conical/tappered/acorn 2. the ball radius and 3. the flat that use a washer .

The 3" studs were for the AL style 2 pc wheels with the wider hub, the reason the nhra mandates the longer stud with those is because people would buy those wheels and not use a ET flat or ET conical nut on them and have like 5 threads of engagement.
The ET nuts are extended thread and those are safe to use than using the factory style conical/taper to grab a few threads.

The length of the stud doesn't make strength, just engagement.
