I didn't see which tires the Mustang was running so I'm not sure if the comparison was fair.
However the ZL1 comes with Ultra-High Performance tires (Eagle F1 Supercar G2's) meant for summer. The hotter the environment the better the traction will be. I can't remember where I read this but here it is, these tires are not supposed to be used in temps below 50 degrees and should never be stored at temps less than 20 degrees. Not sure why but I'm guessing that at such a low temp the structure/chem makeup of the tire is altered.

For you SS guys with the Perrelis. Have you noticed that the cooler the pavement the worse your traction is?

Also, this type of tire absolutely sucks at the strip, even on a hot day.

Let the temperature debate begin, LOL!
