Lateral acceleration comparison
Has anyone seen a comparison between various C7 configurations on the skidpad? I've seen Z51 cars do 1.08G and Z06 hit 1.16G in road tests, but have never seen a base car with or without the ZF1 option (Z51 wheels and tires). I'm speculating here but the larger front sway bar and added rear bar on a Z51 would cut body roll, and increasing the size of the bar on one end alone would reduce lateral traction by applying more pressure to the inside of the turn (sway bar applying downward pressure on that wheel) which is the tire getting the most stress. However, increasing the bar size on both ends with precision would likely increase it. I don't think larger shocks would impact it measurably as long as the pavement is smooth.
It'd be interesting to compare them, but I suspect the difference between a ZF1 and Z51 would be minimal and think a base car w/o ZF1 would still top 1.0G.

I have yet to see any performance tests on a "base" car. It is though they don't exist. I love mine, the ride and handling are good, it's plenty quick and fast. Stops well and corners pretty well.
But, hey, it is a nice looking cruiser. Good enough for me.

Thanks for posting that. I assume the base car figure shown was with the standard wheels and tires, so I would expect a car with the ZF1 option would fall somewhere in between the base and Z51. Those numbers are closer than I thought they would be.

So what you're seeing is that the Z51 tire grips a little bit better in steady state conditions. The number doesn't tell you much about how each car handles transitions, braking zones, or acceleration out of a corner.

Nor does the fact that the ZF1/Z51 tires just because they have a lower sidewall (they are otherwise the same width 245F/285R) automatically mean they have higher grip - Z51 aftermarket A/S tires have nowhere near the grip of the base 18"/19" Michelin's. Since the Z51/ZF1 tires are a slightly stickier compound than the base tires, that likely accounts for all of the 0.03g difference in handling capability between the base car and the Z51.
