Michael Peters has released a small patch for his Indycar Series 2009 mod for rFactor that adds the ongoing IRL season to the simulation.
The patch adresses some issues with road course instability as well as a problem with the red sidewall tire graphics. Make sure to have the full version installed before using the patch.
Just like the popular 2008 version of the mod, Indycar Series 2009 comes with extensive features as fully RealFeel compatible physics, AI files for all IRL circuits and much more.
