From there, it's tuning. From what I understand, the RTD computer would need to be "changed" to work with the new handling characteristics of the car. And, that's where the rub exists. No one knows how to do that, nor has anyone really tried to (like... why bother?)
In the end, start with the easiest things to change: the tires. The vast majority of the handling and ride compliance differences will be made up right there.

The same shocks used in the ZR1 are equipping 08 C6s w/ F55 starting Oct 08 or thereabouts. My Dec 08 C6 F55 had them and I noticed the difference (firmer) re previous F55 generations. Interesting that I commented about that on the C6 forum and was summarily dismissed as untrue (NOT)...
But they didn't make and '08 in Oct '08; at that time they were producing '09's.

The vast majority of the handling, ride, and comfort differences between any of the models of Corvette can be attributed to the tires. Certainly, GM tuned the suspension parameters in the RTD computer for the ZR1 a little differently than they did for the coupe/vert RTD. Things like sway bar sizes and spring rates are different between the cars, and need to be accounted for by the RTD computer.
However, as I already stated: the big difference is the tires. You'd be amazed at how different a Corvette feels when you put something OTHER than Goodyears on it...

I'd agree that tires is the largest factor in handling differences between models.
However, I believe it's only a minor difference in comfort differences. A base Vette with Z06 tires is still going to ride considerably smoother than a Z06. Shocks & springs are the largest factors in ride comfort.
Also, IMO, the RTD software shouldn't care about your sway bars or tires. Only the simplest of controllers relies on hard-coded open loop parameters.

OK guys this is what I would like to know. Is the ZR1 suspension better than all the aftermarket set ups being offered. Are the ZR1 guys that go to the track going to change suspension or are they better off with what they have right now? Does the car still hop to the side when hitting a bump in a turn?
I know some of you have driven both on the track. Please share?
Congrats to all of you that have purchased and hope you enjoy every second.

Heavy springs and sway bars are great for limiting body roll/pitch/dive but they suck at keeping the tires in contact with the road over anything but the smoothest of roads.
