For good conering, precise Ackermann steering geometry agles of the steering arms is required. True ackerman is where the steering arms point to the mid-point of the rear axle centerline. This is most important for low-speed cornering. Some race cars use reverse Ackermann geometry to compensate for the large difference in slip angle between the inner and outer front tires while cornering at high speed. The use of such geometry helps reduce tire temperatures during high-speed cornering but compromises performance in low speed manoeuvres.
