Below you can find a video of the racesimulator with Dirt2. Everything works fine now (the roll and pitch are only 6,5° and 8° or it would be to wild). The jumps can be felt really good thanks to the vertical force that is used for the pitch besides the longitudinal force.

And here you can find a test with NoLimits Rollercoaster to show the extremeties of the simulator test by my wife

For anybody who would be interested, the profile-files can be found in the attachment (profiles.rar). Does anybody know if a profile for Dirt2 will also work for Dirt3, Grid (all these games are from codemaster and use the LFS-plugin).
