The tire's grip loss behavior has been improved by adding controls to better manage slip/grip curves in various driving situations, making tires less lenient when driven over the limit.
grip loss behaviorThe combined grip has been increased, allowing tires to offer a wider range for utilizing longitudinal and lateral grip simultaneously before losing traction, reducing sensitivity on corner exits.
combined gripThe simulation of yaw moment, particularly for cars with rear limited-slip differentials, has been significantly improved by reviewing and verifying numerous factors that impact tire friction and force exertion.
yaw momentThe tire model has been fundamentally reviewed and improved, impacting cars from Mazda MX-5 Cup to Ferrari F40 LM, including GT2, GT3, GT4, and Cup cars, but not F1 or road compounds. The tire model's fundamental aspects have been deeply reviewed and improved to better understand emergent behavior and debug individual factors.
tire modelSteering response has been made much sharper by lowering the tire's slip angle requirements.

A small change has been made to the scaling of self-alignment torque, making oversteer more noticeable and generally increasing FFB forces.

New logic has been implemented to better account for contact patch variation in all situations, influencing where the grip peak is found and adding to the tire's dynamic behavior.

Fix · 1
A bug where the inside cambered tire produced excessive longitudinal friction has been fixed, and camber now has individually controllable impacts on longitudinal and lateral grip.
