Kind of depends on what type of track(s) you are running and under what sanctioning body. I am running under SCCA rules so get a bit of leeway as to INEX rules. Most people that I know tend to run the rear end square to the chassis. As I have both left and right turns, that is my choice as well. Rear end camber is normally used for seasoned drivers at a particular track. I think tire stagger is more new to the set up as opposed to the old tires. With not much of a season to try out the Hoosiers, I think that is where the gains (or advantage) will come from. I could be wrong! Then, throw in the FZ09 engine and gearing. I think if we all ever get a full season to test and tune everything, the racing may get very close. I watched some friends this past season run the FZ engine for the first time out. They must have had things pretty much right on... They were extremely fast! Without a full season to test all the theories, I think it is going to be who can deal with their set up the best.
