Start with factory settings for the OE tires. Adjust down/up depending on shoulder scuffing, heat across the tire after a run. Er...you do have a tire pyrometer don't you? Available IR thermometer at Harbor Freight Tools for $25:

I used 22 front and 24 rear and it works well. My car is a lot lighter, so you may want to creep it up a few #'s
