The same thing happened to me as the friend above.
ON CLEAR DAYS, THE WHEELS GIVE VERY REFLECTION, VERY DIFFICULT TO DRIVE WITH THE COCKPIT CAMERA.
At times the cars change shape, going to the 2013 skin then moving to the 2009 model.
And from a distance the wheels don't show the details, when approaching (like Brawn) they are normal.
Aside from these small details, this is the best mod of a 2009 season ever made. You are amazing, congratulations!
cheers
second, set ur game language to english otherwise u'll get wrong nationalities.
