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

When considering the suspension design for a competition-focused car like the Radical SR3, the unequal-length double-wishbone option is undoubtedly the best for many applications due to your ability to make many fine adjustments to dial things in perfectly for your driving style and the circuit at hand.
