Gearhead999s, thanks for the feedback. Thinking about the tracks I'm running on, I'd say I'm in 2nd once/twice per track. Mostly 3rd, get into 4th on the straights. Based on what you've said, I'm thinking square might still be okay for me.
paintpro21, What about the 10F/10.5R combo vs. square? I had 285 RE-11s (on the OEM 19x9.5 wheel) on my rear last year, moving away from street tires this year and am loathe to give up any rear width... $$ savings by rotating back to front is less important, more important to me is the performance & predictability in handling.
