Are you sitting comfortably?....
The "Ackerman Angle" allows the front wheels to turn by different amounts so that the tracks of the two front wheels are not the same. This allows the inner wheel to track at a smaller radius that the outer wheel. It is necessary to prevent excess tire scrub. The the car's "track" will mandate the amount of difference. In driving very tight "circles" it will become obvious. On a race course where `full lock" is rare it is not as critical.
Named after it's inventor Rudolf Ackerman, this angle defines the correct angle that steering wheels must have to effeciently negotiate a turn. In a standard turn, the wheel on the inside of the turning radius must follow a more severely curved line than the outside wheel. By setting steering arms, one can successfully adjust the turning angle so that the inside tire turns at a larger angle than the outside. This results in better traction around the turn.
Ackerman angle is the angle of the king post which holds the hub, the angle is the verical displacement of the top of the king post rearwards, the inside turning wheel will effectivly move in a smaller radius than the outside wheel, this angle also helps in the self centering of the steering in a straight line.
It was originally patented by Rudolph Ackerman in the late 1800's as a way to reduce the stresses on horse drawn wagon wheels which used a center pivot front axle. The stresses involved were responsible for premature breakage of the spoked wheels used at the front of the wagon.

wow stig, impressive. loving the car guys, its a beast. had some issues though. the brakes where constantly squeky, which i didnt notice at test drive. went back to audi 5 times, they suggested deglaze but eventually resorted to changing the front discs and pads and rear pads to get rid of it? how bizarre! it had only done 11k.
