Adjustments – The changes made to the racecar, by the race team, in order to attempt to improve performance to the car.

AERO Push – A decreased turning capability, mainly upon exiting the turns of the track, caused by the way the air flows from one racecar to another closely behind it, which reduces the downforce at the front on the following car.

Aerodynamics – In racing, the way in which air flows around and under the moving racecar to affect the pressure and resistance of the car.

Air Dam –The metal strip hanging underneath the front grill of the racecar, a few inches from the ground, that gives the car aerodynamic downforce by directing faster moving air near the front to improve the way the car handles.

A-Post – A post that runs from the bottom of the windshield to the roofline on both sides in the front of the racecar.

Air Pressure – The pounds per square inch (psi) of pressure of air in a tire. Drivers often use increases or decreases of tire air pressure during a pit stop as a technique to improve the racecar’s handling and performance.

Apron - The paved part below the yellow line between the race track and the infield.


B-Post - A roof support in the center of the racecar.

Back Marker - A racecar that is running at the end of all of the cars.

Banking - The slope of the racetrack measured from the apron to the height of the outside wall at the corners and expressed in degrees.

Bite – The racecars’ tires ability to adhere to the surface of the race track.

Bump Draft - When a car drafts behind another (see "draft") really close and actually pushes the front car. This makes both, or several, cars faster and is mostly done in restrictor plate racing.
