Starting with Beta6, all physics files are unencrypted.
It is therefore possible to use the "official" cars as a reference to create new cars.
The needed files are CFG, GEOM, TYRE and ENGN. They all are text files.
For the engine curves an editor can be found in the vehicle tools: http://www.kartracing-pro.com/downloads/vt.zip
Everything else at the moment can only be manually edited.
To tune the physics data, there is a debug mode: http://forum.piboso.com/index.php?topic=2314.0
