While I agree its mostly about setup stockish cars need more tire up front. You likely dont have luxury of dialing in suspension and bars like a race car can. FYI I run 295 rears and 285 fronts on the track on same width rims as you. For AX I run 315 rears and 295 fronts.

If you are doing AX no amount of dialing will offset front end push if you are under 275 so go bigger in front by default for AX for sure.
