XSR Setup Guide for GTR2 This setup guide is for use with GTR2 sim racing, although I’m sure it could be applied to other games. Its purpose is to give drivers with minimal knowledge about making their car fast for any given race a resource to go to about how to set their car up. It also helps some of us veterans out. I know it has helped me a lot over the years. Be sure to use this guide in Simulation Mode of the game so that aids don’t interfere with your results for each change you make.
