What are the pressures hot? What kind of spring rates do you run? I ran 46s at Atlanta, but I need a lot more track time to get quicker.
We run 450/700 springs with swaybars ft and rear.
Do you find that the tire go off at end of a session? I have not found any unusual tire wear either.
I can't run the ARRC, but I will try the higher 37/35 next year. Can't stand still the Nissans are coming.
