As for tires, I am not sure if we need to fit 315 all around. It appears that 285 is already quite good. Of course, the wider the better.
My car won't be even close to the level of your car's prep even after 2-3 years. I will do the changes on at a time to really understand how each component affects the car.
This weekend, with my co-driver help, I am surprised to know that the tire pressure still played an important roll on the car even though it's runflats.
As for course, my target will be national type of courses, which should have a balance favoring both light weight small power and heavier big power cars. The course this weekend was a good example, some RX8 in CS managed to be within 3.5 secs behind the ASP cars, even though the course appears to be relatively high speed.
