Gary I understand that but I was surprised that the clutch would be in almost new condition with 30+ passes at the 1/4 mile and street use. :D

I would bleed/flush the clutch fluid for starters:

Remove all the fluid out of the reservoir with a turkey baster, then wipe all the crap out of the reservoir with a paper towel. Then every few months you can get most of the fluid out of the reservoir with a baster and replace with fresh.

It is a PITA but here is what the reservoir looks like on a 01 Z06 with 16k miles:

Yes, I see your point about the 30 heavy uses on the clutch at the track.

The Z peice is a better clutch though and (at least for me) most of the time inspecting a removed clutch is after many miles or one that has been fried.

As long as you weren't spinning the clutch on your launches it shouldn't have been worn too bad after only 12k miles.

It had to be a little shock, though, to see a perfectly good clutch when it was being torn down for a defective one though.

No I really don't spin(slip) the clutch on launches.Yes I was surprised at the clutch.It looked almost as good as the new one.

As mentioned, the ZO6 clutch setup may cure your problems, but if you are going to be drag racing alot, I would recommend a Cartech clutch setup. It has about twice the clamping force of your clutch and I think the Z clutch has only about 20% more clamping force. If you are going to spend the money to get in there and change it, I'd spend the $$$ and get a cartech. they also modify the master and get rid of the line restriction at the same time.

What would this mean if your RPM's hung at the same position but the car fell on its face? thanks.

Well.. are you ruling the clutch out then?
I have a couple ideas.

Watch your batery voltage while driving around town. Also, watch your voltage the next time you bog down.
Where is your voltage at? Specifically when bogging??

I have driven the Z a few times this weekend and it seems to be fine.. I guess I just got it too hot when I did the long burn out.. as I was still rolling when I lit the tires and then hit the brakes (I guess too hard) thus making the clutch slip - then it over heated and didnt bounce back..

Now, I hope that it lasts and works properly and only time will tell and or another trip to the track..

We'll see..

Yep - the RPMs stayed up - however the car wasnt going anywhere as I lost MPH like I was on the brakes.. look at the MPH on the time slip.. then check the time slip in my sig which is what my "usual" MPH is..
