A lot of people go from 265/35 rears to 295/30, myself included, and I wonder if that's really a positive for lap times. I don't know myself.
Can't speculate on the first part, but I can tell you 295/30 will have more grip laterally and on accel than 265/35, resulting in faster lap times (assuming on a proper wheel width of course).

If I could fit wider than 275 in the front i'd run 285 or 295 square, but the front can only handle 275 slicks on my 18x10's so I do 275 square on track.
