Thanks guys.
Lim: The rear diffuser works fantastickly. And then, the "exhaust blown diffuser" setup we did in the middle of the season also made a great difference in slow to medium turns.
MC: I run R6 Hoosiers. Square setup 285/18 all around. Normally shoot for 38-40 hot pressures depending on track surfaces and type. I dont change alignment on-track so some times play with the front presssures to aid in offsetting how off I may be on camber at times. At US tracks such as Pocono and Daytona when running high speed steeply banked courses, camber gets backed out big time and pressures drop on tires a bit. I actually have been considering going to slicks this year to campaign in one particular class, but between the cost per tire and cycles they last, I have been trigger-shy on the decision.... I have heard good things about the Yokos, and obviously the Michelins.....
