Old hold over from when the tires sucked and to get forward thrust was to do a wheelie. Plus most of the stock and super stockers are running 50psi in the front tire if not more.

What's the reason behind requiring metal valve stems on cars running under 12 seconds?

Rubber valve stems flex at high wheel speeds and can fail.

You stage on the spoiler instead of the tire but the down track  beams are on the body and you have now added 12+" to the length of the track. The good part is if you do this you are only shooting yourself in the foot.

google beam tripper and enjoy the read for more stupid drag racing "secrets"

Staging is done with the tires.  The extender or low facial trip the timer in the traps.  It "shortens" the trip.  The Funny car above shows how the front end is pushed down and get to the traps quicker then the front tires.

Yes you *should* stage with the tire, my example is if the car is too low and you stage on the spoiler/front end. It's quite common on the FWD cars as front tire pressure effects height a lot.
