The Official 370Z Autocross Thread

I need some advice. I just started running in the street tire CS class my local SCCA has. I want to upgrade to some better tires, and hopefully get rid of the understeer. The car is 100% stock. What size/type of tires do you guys recommend? It seems like RE-11's are the best option. I'm hoping to reduce understeer by reducing the difference in front/rear width. Am I better off running 275/30 front & 285/35 rear or 285/35 all around? It seems like 285's are a bit of a stretch on 9" wheels in front, but the 275/30's are 1.2" smaller diameter than stock.

Also, what would you recommend for alignment settings on a stock Z? I know were pretty much screwed for camber, but has anyone tried playing around with the other settings?
