Need Clutch Advice
I was driving home from work Thursday and, after pulling away from a stop sign, I got a little aggressive on the throttle. I shifted to second and again was heavy on the throttle when I noticed the rpm raise without the car pulling. 
clutch slip! The car has almost 40K miles on it and I had just taken it to the drags the Friday prior. I am right at 500 rwhp on an 02 Z06 with headers and a TVS2300. I just put NT05s on the back because the Invos just wouldn't hold traction. I knew with going to the track and the way I drive, the stock clutch wouldn't hold up to long. I don't expect to go over 700 rwhp and may not go over 600. I want a clutch that can handle launching at the strip and will drive as close to factory as possible. This is often my DD so it needs to be very streetable. Looking for advice, Thanks.

twin disc, possibly ls9, monster, mccloud etc
the ls9 is going to be the one that drives like stock, but there is some expense in using them in a c5 if i remember right. katech had a kit using the ls9 clutch to make it a bolt in job with the c5
ahh, found it

many of the other clutches rated to 700+hp can take power but ceramic friction materials do not drive anything like stock

In June I went with this clutch -
I ordered it through Cordes Performance Racing in Mesa AZ.
MANTIC ER2 SINGLE STREET SERIES CLUTCH KIT LS1/LS6
Cover Assemblies with the ER2 Groove Design feature have a unique groove pattern CNC machined on the friction face of the Pressure Plate. The groove has been specifically designed to increase the Mean Effective Radius of the pressure plate and assist in heat removal. The increase in the Mean Effective Radius of the Cover Assembly gives an increase in Torque Capacity by up to 8%. Mean Effective Radius is directly proportional to Torque capacity.
By adding the groove to the Pressure Plate, the inside radius of the friction face has effectively been increased. The first 5/16 inches of the pressure plate has all but been removed and added to this, there is progressively less material removed as the radius increases. The net effect of this is to move the effective inside radius further out. When comparing the Mean Effective Radius (Rm) of the ER2 version to the non ER2 version you can see the ER2 version is further out.
This clutch is best suited for the stock replacement on cars ranging from stock to 700 HP. Clutch kit includes:
- Pressure Plate & Clutch Disc
- Pressure Plate Bolts
- Flywheel
- Throwout Bearing

Have an ACT which is good for 650HP. No difference then the stock stuff feel that came out but way less weight. Costly...... but disk, plate and fly balanced from manu and working great.
