Patch SimRacingPL was based on NAP v 1.3. Changes have been made mainly related to the tires. The idea was to create a more realistic model of tire on dry and wet surface.
The changes were:
1. Tires
- The designation of the new slip curves for the tires,
- Changes in the tires grip,
- Changes in the way and speed of heating the tires,
- Changes in impact of temperature on tire traction in case of cold or overheated tires
- Changes in tire wear.
2. Brakes
- Changes in optimum temperatures of brakes,
- The introduction of brake wear.
