Spec Stage 3
I don't think you NEED to upgrade hydraulics, but it is 100% recommended by everyone eveywhere.
It is a very strong pedal feel (requires a lot of power over stock and a bit more than other similarly rated clutches from my experience). It holds power very well, if it lasts, and can be hotlapped at the track without issue. I haven't had great experiences with multiple Spec clutches in terms of lasting very long, so I would recommend looking at other options, but that's just me (and my brother, and a couple friends...).

Our average raced 3+ lasts about 20-25k miles.All the problems I see just make me surprised because we don't see it personally.
As for the blown up SPECS.Yes there was a few and for some reason I think they were all friends which is kind of wierd. I've pulled a few blown clutches and they weren't SPECs but other populer brands.So it happens to all clutches and are ussually caused from a slipping clutch that overheated-bad.
If you race a scattershield should be used.

I ran a Spec 2 for over 40,000 miles no problems other than having to have it balanced by a local shop. Took it out and put a Spec 5 in since I was going with a 408. I had it balanced locally no problems 5,000-5,500 clutch dumps. They have my business as long as they keep putting out good product. Many clutches are installed by people who don't know what they're doing, then they complain the clutch is fkd up, when they installed it wrong.

Sometimes it's improper installation, sometimes it's just not a quality product. I'm sure it's a case by case situation going both ways.
Keep in mind that excessive vibration from either of the following can lead to reduced life and greater potential for disc issues: excessive input-shaft play, bad motor or trans mounts, a bad pilot bearing, excessive heat, excessive shock to the drivetrain, etc... Discs don't just randomly decide to come apart on their own. Realize that I am not attempting to argue with you about this...I just want to make sure that folks know the potential causes for issues of this nature so they can be more adept at trouble-shooting and assessing their own issues.
Pewter, Spec probably sells more clutches than than all the other mfrs combined for LS1's, so there obviously would be a higher failure rate that you would hear about. All I know is my stage 5 has taken horrible abuse and owes me nothing. The 3+ from what I understand is a great product. When my stage 5 goes if I have the $ I'd like to go with their new dual disk, although it seems over priced.
Hey Big...let me know when you are ready to go twin-disc...I always try to help out return customers. BTW...thanks for the support. To give you and everyone else an idea of the number of LS clutch kits we have sold over the years...lets just say that it's north of 17,000 unit. That being the case, I would say that you above statements are pretty realistic! Let me know if you guys have any further questions. Thanks!
That is what I was going to tell the OP. The chatter is horrible at first, but once it breaks in it's great. I also have the spec3 going on a year now and now problems so far.
Agreed Chatter is BAD when its new. When I was a bolt on only car the spec held up great but its been maybe 2 months since I went heads cam and my Spec stage 3 is TOAST. Guess it couldnt keep up with the extra power.
My Spec 3 makes alot of noise when leaving from a stop, it sqeals pretty loud. Is this normal, does it happen to everyone with this clutch? My clutch is is broken in properly and has about 1,500miles on it. Other then that it is great, but im suprised i dont read anything about the noise it makes while DDing it.
But this isn't chatter... When I first got the clutch installed it would make noise and just grab super hard out of no where which is chatter.... now it's broken in and drives great but constently makes this noise when I take off like a sqealing, pretty loud I hear it echo off cars that are next to me.
