Skid Pad Lateral Accel (g): 1.08 0.95
Slalom: 72.8 67.9
Clearly they have moved the handling and grip up the ladder in a very big way - the 4.9 second improvement in the slalom is huge, as is the skid pad improvement of .13 and the 17' reduction in 60-0 braking distance.

Interesting results (+0.13 g skidpad, +4.9 mph slalom, -17' braking). I wonder how much of that was due to improved tires (Michelin PSS ZP developed specifically for the C7 Z51). Reminds me of when Edmunds put Advan AD08s on their long-term FR-S. Saw improvements across the board like that, although on a smaller scale.
1.00 g / 70.3 mph / 107 ft -- FR-S (Yoko AD08)
0.89 g / 67.5 mph / 114 ft -- FR-S (Michelin Primacy HP)
Improvements of +0.11 g skidpad, +2.8 mph slalom, -7' braking.
At the pace tires are improving, I wouldn't be surprised if a lot of that improvement came from the new tires. Michelin seems pretty proud of them.
