I need a clutch and can get a great price on a new spec stage 3 & flywheel. Wanted to see if anyone else has this and if you like it.
So if I understand this, a ZO6 Clutch pressure plate and clutch disk work out of the box with the UUC flywheel. Is that correct?I just put a new Z06 clutch disk and pressure plate in my car today with a Fidanza aluminum flywheel. You'll need a spacer if you go with a good fllywheel (with the exception of the nice UUC alum one.)
I concur. I spend lots of time at the track. If you are not going to the track the Z06 clutch is fine. The 01 and up F-body came with it stock. My 01 lasted 40,000 miles with a bunch of track abuse. In adddition to that I don't need to mention what else use the Z06 flywheel and clutch...:thumbsup:I just put a new Z06 clutch disk and pressure plate in my car today with a Fidanza aluminum flywheel. You'll need a spacer if you go with a good fllywheel (with the exception of the nice UUC alum one.) I ordred the aluminum spacer from Katech (they didn't include the longer bolts (you'll need a pair of 40mm M6-1.0 metric bolts) which aren't common at all stores. OReiley's had 'em. When putting in the spacer, the hydraulic line is moved out, and will no longer sit in the notched recess in the tranny, so I trimmed a notch in the bellhousing, basically just extending the existing notch for the T/O bleeder another 1" toward the driver's side. (It's obvious when you have the bellhousing out).
I say all this assuming you'll go with a lighter flywheel, as it's almost a sin to leave that dual mass flywheel on there if you've got the tranny out to do the clutch.
If I had a spare $1500 then I would also opt for the McLeod twin disk setup too. Then the next weak link is the diff, or the driveshaft...take your pick. It's hard to imagine any single disk setup being better than a multi-disk setup, and McLeod makes good stuff.

I must admit, it makes me a bit bitter to see that McLeod will sell essentially the same clutch setup for roughly $300-600 LESS for everything else, but for the LSX powered cars with the T56...chaching, it's $1500. Ouch. Oh well, quality costs, and I'm not making big power yet anyway, so the budget Z06 setup and alum. flywheel were good enough for me. Engine revs quicker too, and it's a noticable seat-of-the-pants increase in acceleration in 1st gear, and feels a bit better in 2nd too. By 3rd it feels about the same, but deep down it makes me happy knowing the car weighs almost 40# less without spinning the stock flywheel. Common sense says zinging the motor up there and dumping a 51# flywheel worth of KE into the drivetrain...well that energy's gotta go somewhere or something's gotta give. A lighter flywheel is more drivetrain friendly, but can add a bit of NVH. I can't beleive Caddy compromised and went with the dualmass unit because of of that.
Sorry to be so long winded by throwing some rants in there.
Anyone want a fair deal on an almost new Z06 steel flywheel? Or an even better deal on a boat anch...err..stock dual mass flywheel?
I can't speak with certainty since I haven't handled a UUC flywheel myself, but I'd say that NO, it won't work with a Z06 pplate and disk. The picture of the UUC alum. flywheel I saw appeared to have a recess machined into it (or standoffs for the stock dualmass type pplate, but either way was you look at it the dual mass flywheel is very different from a Z06 flywheel. The Z06 flywheel and all the other lightweight flywheels for the LS1/LS6 engines is about one inch thinner in profile and the entire friction face is flush with the mounting surface. The dualmass has a recessed friction surface, that's part of what makes it "unique" imho. I'll post a pic later to show my dualmass next to a stock Z06 flywheel.So if I understand this, a ZO6 Clutch pressure plate and clutch disk work out of the box with the UUC flywheel. Is that correct?
threadjacking :thepan: sorry
Good for you. I have been following this thread and had conluded that the Spec 3 clutch is likely quite serviceable altough it may not be the equal of clutches costing twice as much.Well I went ahead and bought it for $550 so it will be here this week and installed on the weekend. I will report back and let everyone know. This will be my first ever aftermarket clutch on any car.
I went through this too, and ended up with Exedy. Two years and repeated track use and I'm still happy.not with all the horror stories Ive heard about Spec. I considered them, could even get em at distributor cost, but passed for Textralia. Better clutch, more clamping power.... IMHO.
