Ackermann steering geometry determines how the front wheels angle in a turn, and it plays a big role in how a car handles. In simple terms, it’s about the difference in steering angles between the inside and outside front wheels. Positive Ackermann means the inside wheel turns sharper than the outside wheel, while negative Ackermann does the opposite. Race cars typically use negative Ackermann, especially for high-speed circuits. In racing, the outside front tire carries the majority of the load
