Why Ackermann is so important when it comes to drifting? By changing Ackermann setup you can radically change how the leading and trailing wheel will perform when...

Ackermann steering geometry is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn that need to trace out circles of differing radiuses.

In simple terms, Ackermann geometry or steering geometry defines inner and outer wheel (leading and trailing in drifting) steering angle difference.
