I plan to be running faster than 200 mph.What is the minimum size of the rear wing I will need on my Top Dragster? 

Answer:

In the 2016 NHRA Rulebook section 6B Top Dragster on page 8, body, it states “A rear wing is mandatory on all cars that exceed 200 mph; minimum area 360 square inches, maximum 750 square inches, minimum height 55 inches (measured vertically from trailing edge to ground).  Spill plates must be flat/straight and parallel and measure a minimum of 50 square inches each.”
