Next time, try 37f 38.5r on the 070s and let us know how it feels. Those are the pressures I use and I like the slight rear twitcheness (OMG, that word again )GSXR said:If this is your first time. Run stock. Don't change anything except your tire pressures. I'm running 37F and 37R which worked pretty well but I haven't had enough autox's in this car to figure an optimal pressure yet. Other than that have fun and hang on. This car is friggen fast.
