NHRA Top Fuel ‘mud flaps’ will be optional for next four races
NHRA officials have announced that side-mounted aerodynamic body panels in Top Fuel, commonly referred to within the class as “mud flaps,” will be optional for the next four races while NHRA evaluates their effectiveness.
NHRA officials have announced that side-mounted aerodynamic body panels in Top Fuel, commonly referred to within the class as “mud flaps,” will be optional for the next four races, starting at the upcoming NHRA Arizona Nationals in Phoenix on March 21-23, while NHRA evaluates their effectiveness of reducing rear wheel loads without significantly impacting other areas.
The NHRA Technical Department will reassess the mud flap after the four-race trial period, working with Top Fuel teams to gather as much information as possible.
If no mud flap is utilized, the side of the Top Fuel body must be covered with a replacement body panel, with no bare chassis exposed.
