Home  Looking beyond graphics; tires is half a racing simulator's work. The physics model is the other half. The graphics are the other, eh... 

What is the Pacejka Player?
This is a tool to modify the relationship between on the one side load, camber, slip angle and slip ratio, and on the other side (the output) longitudinal (tractive) force, lateral (cornering) force and aligning moment.
It is NOT for the faint of heart, but useful for those who wish to tweak the way tires behave. On the other hand, it may be one of the most interesting features in Racer.
Mathematical Basics
The Pacejka magic formula is explained in mathematical terms on a different page.
Standalone application
A separate Pacejka Player that works independently of Racer can be downloaded here. You don't need Racer for it to work; it loads industrystandard TIR files. Just use 7zip to unzip the application folder somewhere on your disk, and run from there (no need to run an installer). Here is a log of the changes in the standalone Pacejka version:
The interface
The image below shows an example of the interface.
More to come...
