I have a set of Kuhmo V710 on the way for YellowDog. We have a set of 7" Cookies to run them on and wonder if any would car to suggest a starting point for pressure. They are 205/50/15's and the car is set up with Bilstines, 21mm front torsion bars, 19" F sway and 180# rear springs. 38 f and 40 r seemed to work well with the Falkin Aziens we were running. Autocross only. Do these need to be heat cycled? Specs don't mention anything about it.
