At 220 MPH, the physics engine is operating on at least 50 different variables over discrete distances of 8 1/2". I created an Excel spreadsheet that allows me to tune my car fairly well. However, since tire slip is pretty difficult to model accurately, there's significant error between what the spreadsheet predicts and in-sim results, i.e., approx 5% or so.
i know these guys through their sister and think i am going to have to give it a try in the near future
