That 12.7 is a good number, no argument there. But to pick up 1/2 of a second in the quarter, much less 0 to 60, requires more than the difference the tires make. Probably most of that difference is in the stickier tires and a couple pounds less of unsprung weight. I would like to see back to back 60 foot times by the same driver in both an SS and a 1LE.
I know the gearing is different, but with the transmission changes the overall gearing is roughly the same. And both the SS and 1LE will benefit from the optional exhaust and electric power steering.
