You are correct, going +10mm is not significant in performance / grip and has no affect on the car electronics for the street. I went to 245 / 275s because they were a bit cheaper in MPSS but with my recent MP4Ss, I went back to 235 / 265 (and N0 designation).

If you are looking for track performance, 255 / 285+ is worth looking into (with a lower aspect ratio to keep the overall height consistent).
