Determining the best line is an essential skill to master for both track days and racing events. = Angle of the trailing edge The mid-perpendicular to the reference chord segments, such MN is called the profile or skeleton mean camber line. If your front end is not aligned, you may find your car veering to the right. Maximum Camber Line: The maximum distance of the mean camber line from the Chord line. It is also important to be aware of the fact that because camber is a continuous curve or radius of the strip, if you have a given amount of camber in a specific distance, if you double this distance, the camber will increase by four times that amount. Longer lower A-arms can be used to increase static camber, and so lead to less of a need for camber gain in cornering. Mean Camber Line = Line drawn half way between the upper and lower surface of the aerofoil. These procedures and the mean line. 98 inches per mile or approximately 8 inches per mile (squared). This is because Steering Axis Inclination is a non-adjustable angle. Compute the mean camber line coordinates for each x location using the following equations, and since we know p, determine the values of m and k 1 using the table shown below. Note: Be sure there is no loose or bending in the suspension or in the steering components before attempting to tune your vehicle. By using all of the available space on the track, cars can travel in a straighter line and travel faster before reaching the limits of grip. Deck cross-slope, CS = 0. The locus of points midway between the upper and lower surfaces is called the mean line, or camber line. Camber: When you lower a truck you cause negative camber. The easiest way to envision what camber looks like is to view the wheel and tire head on. A car with 0° of camber would have the wheels perfectly straight up and down; perpendicular to the ground. where yt(x) is the thickness function, yc(x) is the camber line function, and θ=tan−1 dyc dx (A-3) is the camber line slope.
