Clutch Recommendations
Did a search and couldn't find much.
2002 base model
So I'm thinking my clutch is on its way out, its all the way at the top (highest point) before it fully engages. Gears shifts smooth and its not slipping or grinding yet but I'm thinking I should get it replaced asap. Its the stock clutch car has 58,xxx miles. The pedal is also seems loose but that could be normal as far as I know as this is my first vette. I've flushed the fluid and got all the nasty fluid out.
Anyways I'm asking for recommendations on which clutch to get for replacement? Will be having a shop do the change and they quoted me at $2000 with oem clutch and resurfacing flywheel. I'm trying to save on a clutch but don't want a cheap one that'll go out anytime soon if that makes sense. Let me know which route I should go please. Thanks!
Also car is stock and only mods a plan on doing are exhaust, headers, intake and tune.

Year of car, base or Z06?
Are you certain the clutch is going out?
Probably Luk clutch, which is the brand they came with new, there are 2 Luk choices, I'm thinking one is for the Z06.
Also I think they come with a new flywheel, however you may need to have it balanced.
Also want to put in new pilot bearing, slave cylinder, add a remote clutch bleeder.
Some say to put LS7 clutch on C5, but it is more heavy and make car feel slower, I'm still on my stock clutch at 90,000 so I have no experience with clutch choices personally, but if you are keeping near stock, I would think stock Luk clutch should be ok, maybe get the heavy duty version.

Chose 2010 Z06 just to see, this kit and flywheel don't cost that much more, I have read some say LS7 clutch/flywheel makes car slower, or feel slower. Member Pounder has one and he said it drives fine, maybe you could message him and ask if he doesn't reply.
I would like to hear more about LS7 clutch on C5 making it slower.

LUK 04905 is an LS7 clutch.
The LUK clutch kit you found on ******** for a 2010 z06 is the same as 04905 minus the flywheel, pilot bearing, and newer slave cylinder. I've installed multiple 04905 kits in fbodies,gto, and ybodies. The flywheel, disc and pressure plate are the same as an LS7 kit ordered from GM.
The stock LS6 clutch kit weighs between 51-52 lbs
The stock LS7 clutch kit weighs between 58-59 lbs. The difference in power loss would probably be between 5-7rwhp across the power curve going with an LS7 over an LS6. But the LS6 clutch can't take more then 400rwhp and doesn't like to be repeatedly abused unlike the LS7, though neither clutch is recommended for repeated strip use.
Their are aftermarket aluminum flywheels that can be bought to lower the overall weight of an LS7 kit. The Ram aluminum flywheel that weighs 16lbs drops the LS7 kit weight to 46lbs, and also the Fidanza aluminum flywheel that weighs 12lbs drops the LS7 kit weight down to 42lbs. Though their are cons to running an aluminum flywheel, those topics have been thoroughly discussed on the forum, and I won't go into detail because it is entirely subjective.

Also mmo24 make sure the shop is well qualified on removing the drivetrain from a 97+ corvette, the price of labor looks to be alright for a small automotive shop. Most of my local GM stealerships here in california charge between 1800-2200 in labor 
for a clutch replacement for a C5-C6 corvette.
edit, also make sure to get the new clutch assembly hot balanced to your original clutch kit, if not drive-train vibrations will be more apparent depending how off balance the new clutch kit is to the original.

I might just have them do it but supply them with the parts I want, which are much cheaper.
Here's the quote from the local Chevy dealer:
Per your request, below is a quote for having the clutch replaced on a 2002 Corvette. This quote does include the slave cylinder, which is recommended but not required for the replacement of the clutch. Replacement of the slave cylinder will be optional based on what you wish to do.
Clutch Kit (w/ Flywheel) $780.70
Slave Cylinder $213.44
Labor: $1002.00
Subtotal w/o tax: $1997.14
The required GM parts would be coming from Reno and would take 2-3 business days to ship to our facility to have the repair completed. Once the vehicle is put in our state of the art facility and with one of our factory trained Corvette experts, the repair will likely take 2 days of wrenching time from start to finish.

hey I just got done replacing my own clutch, master cylinder,and slave cylinder. plus the remote bleeder, I had ordered a repset clutch kit from rock auto, and they sent the first one with wrong bolt s, and the second one with the balance marks off. I finally went to , CARID.COM , they have the repset clutch kit for 237.00 , plus I got my parts in 3 days, with correct balance and special instructions on matching the flywheel balance for my corvette, ( as each motorr is balanced with the clutch installed) wich is very mportant to get correctly, because the torktube acts like a tuneing fork, and will magnify any vibration. .p.s. to balance flywheel , lay old one next to new one with the keyways matching and look in the holes around the perimeter of the flywheel and u will see a couple with a plug in them and a paint mark. just knock them out and install in the same hole on the new flywheel.

Consider the torque tube bushings while you're in there. Slave cylinder too. There's some redundant labor with the exhaust if you were going to pay someone to do the headers/exhaust you mentioned up top.

Can't seem to figure out what brand of slave to get. I'm getting a Luk LS7 clutch and Luk master, not seeing a Luk slave though. Are the Dorman one's a good or bad choice? Also should I be getting a different brand master or is Luk a good choice?

the new cliutch works great. did you know that the clutch assembly from the factory is self adjusting , you feel pretty much the same position and feel on the clutch pedal through out the life of the clutch till the very end, then it drops fast. one sign I had was the sticking clutch pedal. so don't replace the clutch without doing the whole assembly and the slave cylinder with the master cylinder and don't forget the remote bleeder, its almost impossible to bleed the car without it.. just do a search on the forum. you can learn a lot on this site , I pretty much learned how to change mine myself , and I had fun doing it.
