Perhaps not to mention N52. Trying to think of little things I can do to enjoy the car more and ward off the new car bug. Not inclined to spend any money on cosmetic mods. That said, I don't want to degrade the turn-in or NVH of a DD in the process.

For street driving you will not notice a huge difference between 255 and 245.
From this and your other posts, I think your bottom line is, if 8.5s are the wheel, 255s are too big and thus 245 would be preferable in comparison(?)
