The nuts are glued in place on the wheels already. When it goes on, all they have to do is tighten them on with an impact wrench.

Probably just because it more traditional to use the 5 lug nuts and it has stuck through the years without something to be changed. Also, these cars are modeled after actual models of a certain maker. Each car has to be an optional 4 door model design by its specific manufacturer. This means that any car that doesn't have a 4 door option would not be able to be used in cup. This is why Ford runs the Fusion, Chevy is the Impala and Dodge is the Charger and Toyota is the Camry. This is why you don't see Mustangs, Camaro's, Challengers and stuff like that in Nascar. So basically they want to keep it as close as they can to a basic passenger car that you or I would drive. Also, the guy is right about the pit stops. It takes between 10 and 12 seconds to put in 2 cans of fuel anyway so that's the most important thing. It wouldn't make sense to hurry on the tires and still wait on the fuel to go into the car.

The Lugnuts are put on the wheels with an adhesive already--The Impact guns use a spring loaded SOCKET so when they take the old wheels off the spring kicks out the used lug nuts then its just ZIP zip zip After countless hours of training. Most pit crews have--BEHIND the wall a wheel mounted on a stand so the Tire Changers can practice during Green Flag Runs!!!!!

The lug nuts are glued to the wheels with something like 3M Fast-tack, it is weather strip adhesive. It dries quick an is similar to rubber glue.
It stretches when dry. They place the wheel over the studs. The glue stretches and the nuts sit over the end of the stud.
Then the Tire changer just has to hit it with an impact gun to tighten it down.
If one happens to fall off, he will have a couple extra glued to the back of his gloved hand. Just pops it on and tightens it down.
Run to the other side of car and repeat.

There are coil springs that hold the lugs to the wheels, so all they have to do is catch the lug with the socket and hit the air switch for the impact wrench.
