Issues with 255/40/19 front and 275/40/19 rear
I've done some searching on the forum but can't find anything concrete.
Will I have abs or traction control issues with a 255/40/19 front and 275/40/19 rear setup?
I have a set of stock boss 302 wheels (9F/9.5R). The 255 diameter is 27.2 and the 275 is 27.7
The 2015 Peformance pack cars are running the same 9F/9.5R rim size and tire setup.

No, you will not encounter any problems with ABS or TC.
I've been running the next size up of each on my 2014 GT, 265/40ZR19 (27.4") front on 19x9's, and 285/40ZR19 (28.0") on 19x10's for the rear for the last two months.
To add to that, the factory 2012-2013 Mustang Boss tires were 255/40ZR19 (27.2") with 285/35ZR19 (26.9") on the rear, the rears being shorter than the fronts.
And to top this off, the 2011 thru 2014 Shelby GT500's used 265/40ZR19 (27.4") on 19x9.5's up front with 285/35ZR20 (27.9") on 20x9.5's out back. This combo is more odd for two reasons, wider rear tires on the same width wheel as the front, plus the rears were taller overall while using a 1" taller wheel.
These are the examples I know of in recent history where factory Mustangs have come equipped with different height and width front/rear tires.

KN7671 how do you like the 265/40zr19 on the front?
I thought about going with 265/40zr19 up front and 275/40zr19'in the rear, but wasn't sure if the front would feel soft or spongy.

They grip really good, no squirm at all, look better than a 255 on a 9" wheel, more squarish, and provide more rim protection for those times when you park too close to a curb.
The only problem with the 265/40ZR19 is limited tire selection, so unless you're willing to pay for the 265/40, go with the 255/40 and 275/40 should work pretty good.
I don't like the 285/35 in the rear unless the car is lowered at least 1.5" in the rear, as the fender-to-tire gap with a short square tire in the rear fender well is fugly.
