Clutch suggestions!!!
In a couple of months I'll be putting the car back away for the winter and I am planning on pulling the drive train to change the slave cylinder. I believe that I have a bad throw out bearing. What else should be changed at the same time. The car has 85K miles. I'm gonna replace the pilot bearing, torque tube bushings, slave cylinder/bearing unit. The car is mostly stock besides LT headers and CAI. I would like to go with a heads/cam combo in the near future though. Should I go with a aftermarket clutch or a LS7 clutch. If I should go aftermarket which one should I go with. As for power I would like to be around 500 at the motor eventually so I think the LS7 would be sufficient. Please let me know if I'm missing anything. Thanks.

Sorry been wanting to use the (beatdeadhorse) icon for a while
But yeah the 12" DF is the way to go. My Z sees about 12 runs a season at the 1/4 mile with a 100hp wet shot and pretty abusive street use and still engages buttery smooth.
Get a remote bleeder kit. I recommend the TPE kit it has the correct slave cylinder fitting that doesn't need a crush washer to seal. See this thread for more details.http://forums.corvetteforum.com/c5-t...he-market.html
FYI make sure you take notice if your flywheel has been blessed with extra weights. GM sometimes added weight to the flywheel to compensate for the engines not being balanced properly.
If you do have them, the new flywheel/clutch/pressure plate has to be balanced to match the old assembly or you will have harmonics/balance issues.You can try and move the weights from the original to the new but i would recomend having it balanced matched, its to much work to drop everything if it has vibrations down the road. I was blessed with extra weights and ended up resurfacing the original flywheel.

I used a Centerforce TO bearing instead of the stock one, using the stock slave cylinder. P.N. N1777 Might be overkill, but I don't want to ever tear into my clutch again,seriously. Just FYI, I'm using a RPS twin disc organic clutch/matched flywheel, and a Tick master cylinder, which was a bitch to install.

I'd recommend one of our Level 2 Premium Monster kits which will include everything you're looking to upgrade and easily hold the 500hp you plan to make in the future. Let me know if you have any further questions, Chris

Not tying to hi-jack your thread, but since Chris chimed in I was wondering if monster has any plans to bring back the 3.5 clutch. I loved this clutch in my camaro and would love to put this in my C5Z.

Glad you liked it in your set-up, but unfortunately the answer is no as for some peoples driving style the full faced .5 models didn't disipate the heat well enough and we will soon have a new line of twin discs out that will provide super smooth engagement with super high holding capacities! How much power are you planning for your Z06?

And I would love to try the twin.

Anything BUT a Monster Level 3. If youre running on the track only, then its fine. If you drive it on the street for the most part, youll glaze up the flywheel and psi plate and it will make the stupid, most embarrassing noise in the world. Every time you take off your car will sound like a POS. You can clean the glaze off by doing some high rpm launches, but the noise comes back very soon after returning to driving normally.

Love the Centerforce DF. Take the counter weights off before install...unless you like hearing the chatter that they make. Took mine off and the clutch is perfect.

Fidanza for me. The car revs much more aggressively with the lighter flywheel. It took a bit of getting used to at first compared to the LS7 flywheel and clutch. I'm just sorry I didn't make this change sooner. The LS7 clutch setup sucks.
