The three different steering setups explained: Parallel Steering / Positive Ackerman / Negative (Anti) Ackerman
The inside wheel drags unnecessary because of the tighter inner arc.
No tight turning possible.
Very manouverable at high and low speeds.
Predictable steering behaviour.
Low tyre wear.
Not as fast and tight turning angles possible as with an anti ackerman steering setup.
Negative (Anti) Ackerman
Tight and fast cornering possible due to weight shift towards the outer wheels whilst cornering and therefore more mechanical grip.
Greater wear on the outer wheels.
