rear tire for rays 275 or 285

[Jhill]

Ok so I know a lot of people jump rear size for the big tire look but I am asking for a strictly performance application and not wanting to throw off the handing which size to choose for street and occasional track. I already ordered some s04 in stock size but have till wed to change mind of rear size to 285. I know the nismo is 285 however it is also 10.5 in wide rim vs 10 on sport rays. 10 sits perfectly in the middle of a 275 fit (9-11) where it is on the narrow side of a 285, 9.5-11. So will tire squirm be an issue in hard turns? also circumference difference of 26.6 vs 26.9 again not much but will it be an issue for pure handling?

Thanks for any input or opinion.
