I ran my first event with the Michelin Cup tires after throwing out my Toyo S1-R's. (because the sidewall is too soft) And let me tell you, these tires are "Wicked Sick" for the track. They're like super glue!!!

If you're interested, for the OEM wheels, I put 225/40/18 on the front and 265/30/19 on the rear. I heat cycled them myself and ran cold pressures of 33 front, 38 rear.
