I totally agree that training the driver is key. I am training every time I am out there and I am sure I have a lot to learn. I am not looking for these to increase my laptimes. If they do that is great. I am looking for a more confidence inspired ride. I could care less about laptimes as I do the DE's for fun.
The car feels tight on compression and does not roll too much, it is that I just can not stand the fact that a 60-70k dollar car feels floaty on re-bound. It also takes time to regain composure once the suspension has been unsettled. My wifes prius does not feel near as floaty. Stock suspension just larger rims & tires.

I put Koni FSDs on my '08 coupe and it made quite a difference. Calmed down the rear end considerably, no hopping around on rough surfaces in curves. The car still had the RFTs on when I upgraded to a Z06. It appears from what I have been able to read that the FSDs are not tested/ recommended for the Z06. I do not know why that would be as the cars are not that far apart in terms of suspension.
For a few track days a year, I would concur with those who have recommended damper and tire upgrade.
If anyon has used FSDs on a Z06, I'd like to hear from them.

I understand, those of use that have pushed our C5 Z06/C6 Z51/Z06 have the same issues the number one problem are the cheap dampers; number two are the runflats. I'm just saying get some good tires and a few hundred dollars worth of dampers and you may not feel the need to get the full coilover setup. But if you do then you will have eliminated the two common problems and will know exactly what you would want the coilovers for.
As for dampers I presume you mean shocks. I have looked into that and was told by many that for the street side they would be great but on the banked turns at Cali Speedway the coilver would be more stable because it would not be compressed as much there which would make for more stability on track.
Like I said I do goto the track just not a lot.

Its not just the shocks on a coil over package. Another feature of a coilover is the fact that the spring can be changed quickly to another spring with a different rate. Big reason they are used in racing. We had 20 or 30 different rate spring sets to use in tuning the car to match the track and driver. The shock ( damper ) is tuned to help the balance of the car and also propertly damp the spring in use. When you get into the tuning deal you will find that the shock (damper) is used more as a timing device as to when the load of the suspension is actually put into the chassis. Its not just hard or soft settings, but, trying to load and unload the tire without upsetting the balance. And as stated before, if you have an adjustable setup, and don't know what you are doing with adjusting it, it can be dangerious with understeer/oversteer at different speeds. Talking at the limit,,, not street use where anything will work. I constantly read on CF about how this or that "FEELS" better. Not that easy, you need to test and prove improvements with time slips or lap times.

Bottom line: dampers should NEVER be used to limit spring compression, because they can only delay it, not prevent it.

Yes they do help! Especially with the new drag spring package Pfadt offers along with the coil overs.
Being able to firm up (high dampening and rebound) the rear of the car, then lighten the front end, and control droop to a certain degree helps the car transfer weight and promote more traction. So now having full control of ride height and then dampening and rebound, you can better control the characteristics of the cars launching abilities, and promote better friction patch to the tires. (again tires are just as important)
We have used these coil overs on many of our 9 second c6's,and the new upper mounts defiantly made a noticeable difference in complete ride height adjustment.
Good luck on the quest!
