Grille/Screen
#31520 from Michael Kamalian · Not recommended · Minutes (2021-12 Fastrack)
Thank you for your letter, but this change is not recommended. The rules state that an air-dam can be added to the front of a
car, but that its opening must maintain the size, shape, and location of the stock air passage/opening in the stock
bumper/grill. The rules also state that a radiator screen can be added. In the past however, competitors were circumventing
this first rule by torturing the second rule, by adding screens directly to the opening at the outer profile of their cars, and then
adding tape to the screen in order to reduce the amount of air entering their engine bay and improving their aero. This is why
this additional wording was added, requiring that any added screen had to be at least 2" back from the opening, in order to
maintain some depth and profile to the grille/air-dam openings.
