straight from the horses mouth from one of the guys who works for the track:

You need a helmet, goggles (glasses face shield), leather jacket, leather over the ankle shoes(boots), and leather gloves to go down the track. If you go over 120 mph or faster than 9.99 you then need full leathers and an nhra license…
i knew i could go faster than an 11 and still be good. in your face, kawa.
