Tune sweeper hangs on an item driver#
Adjustments can be made to the car that puts more "bite" into the rear tires by adding weight or wedge to the car.Ī turn in which the driver cannot see the apex or track-out until it is reached. The amount of traction that a race car has at the rear wheels.
Used in the expression "jumped on the binders." The driver being flagged has no obligation to do anything other than be alert, maintain the racing line and avoid intentionally obstructing the faster car.īrakes. This flag is displayed by corner workers around the track to signal to a driver that a faster car is either approaching (steady flag) or attempting a pass (waved flag). It may also mean that officials have already decided the car is to slow or too dangerous to continue running, as when it has a serious oil leak that makes the track slippery. The signal for a driver to come into the pits, usually to allow officials to inspect it to determine whether it can run safely after an accident. Primarily used at apexes and track-out points as a driver’s aid. Raised sections of asphalt or cement which runs along the inside and/or outside of a turn, usually painted colors to offset it from the track. On some road courses, certain turns may actually be banked outward, a very difficult type of corner known as "off-camber."Ī turn that's inclined so the outside area is higher than the inside area. On oval tracks, the corners are often tilted inward to provide faster speeds. When a car doesn't tend to over-steer or under-steer, but goes around the racetrack as if its on rails, it's said to be in balance. When a driver takes his foot off the gas pedal (all the way or part way), he "backs out" or "lifts off." To slow down often said of a driver who is attempting to pass and realizes he can't make it, so he backs off to try again later. BĪ car running off the pace near the rear of the field. It is usually flat in comparison to the racing surface. The paved portion of a racetrack that separates the racing surface from the infield. This allows the driver to accelerate earlier and harder, gaining maximum speed down the next straight. In racing, a driver will often use a "late apex," turning into the corner a little later than normal in order to straighten out the last part of the corner. The geometric inside center point of a corner. The angle is varied by track to produce optimal down-force and minimize drag.Ī lateral torsion bar used to resist or counteract the swaying force of the car body through the turns. If his race vehicle was "tight" coming off a corner, a driver might request a slight air pressure increase in the right rear tire to "loosen it up." An increase in air pressure raises the "spring rate" in the tire itself and changes the vehicle's handling characteristics. With the advent of radial tires with stiffer sidewalls, changing air pressure in the tires is used as another setup tool that is akin to adjusting spring rates in the vehicle's suspension. The air dam helps provide aerodynamic down-force at the front of the car. Usually adjusting the angle of the spoiler creates down-force and gives more grip on the race track.Ī metal strip that hangs beneath the front grill of a stock car, often just inches from the ground. This is a term used to describe the changing of the direction of a spoiler or wing on a race car. The application of this study to racing is credited with much of the sport's recent progress as teams learn more about drag, air turbulence, and down-force. The science of understanding different forces acting on a moving element in gasses such as air.
Therefore, down-force on the front of the trailing vehicle(s) is decreased and it does not turn in the corners as well, resulting in an "aero push." This condition is more apparent on the exit of the turns. When following another vehicle closely, the airflow off the lead vehicle does not travel across the following one(s) in a normal manner. AĬommonly used abbreviation when referring to the all-important science of aerodynamics. Don't wonder about the meaning of these words ever again. Here are definitions of both legitimate words, slang words and phrases commonly used in sim-racing. If you're gonna sim-race, then you better know the lingo.
