You have rolling resistance and proper 'alignment' to consider. Am sure others here may know the optimum setting for your car at a given track, since each track could need a slightly different setup. Dry and wet setups can also vary of course. Do you have a pyrometer, as after a nice 15 minutes of running them 'hot' you could check the tires and see the temps across the contact area and adjust accordingly. Camber plates are nice to have if you plan to track often. i assume you're going to have extra set(s) of rims with one having R-compound/slicks, a set for intermediate/rain, and perhaps street tires.
