Some other things to note from their web site, "Racers Handbook":
All pit vehicles must carry a NHRA NED pit vehicle sticker. To obtain a sticker, the owner must complete a special waiver and pay the proper fees ($10 for the year).
The use of any temporary or permanent shielding, including paint, that obstructs the driver’s vision that is attached to the helmet, window, windshield is prohibited.
I assume the class rules (except ET cut-off as noted on the flyer) will be the same as their regular bracket races, such as:
Quote:
