A Z07 might be the perfect car for you! It will be far from the perfect car for all Z06 orders, due its much greater spring rates, probable (but not yet confirmed) stiffer sway bar bushings, re-calibrated firmer MSRP shocks in tour, sport and track modes, and it's required aero package.
As Alex MacDonald, Z06 Chassis Engineer, said to me, when you have much stiffer springs, with their consequent much greater compression and rebound rates, one needs to correspondingly re-calculate the shocks to absorb those stronger actions and reactions. Hence, even in tour setting, the MSRC shocks will need to be, and will be, much differently calibrated.
Perhaps this is the key fact that some previous posters have missed, that once you make your springs much stiffer, not matter what you do with your magnetic selective ride control shocks, the ride can not be calibrated as if your car did not have the firmer springs.
Here is more specific previous information that will help all.
And, as always, that is why GM gives us different options, so we each get to choose what we we want, from a Z06 "enthusiast's" car to a "track extremist's" car. Some will track the Z06; most will not; some will use it as a daily driver, others for special occasions, others for cross country trips.
We each get to choose whether we want the Z07 package or not.
