We have ran some 241's. We have all the mods possible set the ratio's on auto 1/2 way to wide. Then adjust 6th gear to no less than 1.00 and final to 2.00. It almost feels real. What freeks me out though is in the 1st turn when the gravel on the asphalt is like going one way and the yellow line at the top of the wall is going the right direction. I know it doesn't make since.
