What else could they have done that would allow it to compete with the ZL1 in the turns? I don't know if the 300lbs. less weight will be enough to offset the difference.

I've seen two head to head comparisons between the CTS-Vs and the 12 GT500, and one of them the GT500 won by .2 seconds (C&D at VIR) and the other the GT500 won by 1.5 seconds (R&T at Spring Mountain).
So in that comparison, we've got IRS and MRC vs. LRA and nonadjustable suspension, essentially equivalent HP and equivalent tire sizes (the GT500 has 265 fonts, btw, not 255), and about a 380 pound weight difference.
ZL1 vs 13 GT500, we've still got IRS and MRC on one side, but it's vs LRA and adjustable suspension (allowing SVT to go more aggressive in their tuning) on the other. Instead of similar tire sizes, the ZL1 is 20mm wider. Instead of similar HP, the GT500 has a 70-90 HP advantage. Instead of a 380 lb weight difference, it's a 270 pound weight difference.
So, main things going for the Shelby
100-120 HP more than 12 500
Better suspension than 12 500
Already had a road course advantage over the CTS-V
Main things going for the ZL1
24 more HP
80 pounds lighter
Wider tires
Who's gonna win? Tough to say, I think. Anyone that thinks either one is going to blow the other away is probably full of baloney, I think it's going to be very close.
