And also i would like to add by saying that people realy give spec a bad name when their clutch goes out but it is due to inproper install fortunatly i had a tech at the goodyear i worked at do it and actualy did a great job for free.
I just took my car for it's first drive with it's new spec stage 3 clutch and flywheel and it's new strange 12 bolt. I replaced all the hydrolics along with the clutch and installed it to GM'S specs as SPEC says to in their instructions. The clutch chatters pretty bad if I try to start off without giving it much gas but if I bring the RPM'S up a little bit it seems to do much better , so I'm thinking it just needs some miles put on it to break it in and hopefully it will settle down some. I certainly hope so anyway!

allways wonder about the break in period for clutches as I can't see non street egal cars putting on 400+ miles to break in a clutch, especially drag cars.
any thoughts?

Balance, balance, balance. Anyone that purchases any SPEC clutch....get that **** balanced before installing it. I believe this is where a lot of you guys have problems with them. Take the extra time and $50 and take it to a machine shop.
Install it correctly and break it in correctly. DO NOT SLIP it all durring the break in period.
I'm on my second SPEC 3 so far and love the clutch. My current one has 4k on it with absolutely no chatter and handles anything I throw at it. My last one had about 20k on it and was abused majorly. Anyone that buys one of these, take the time to get it balanced, install it correctly and break it in correctly and you shouldn't have any problems.

I had the spec 3+. It chattered at first for about 200miles. When it broke in it felt great. Just like stock. Never slipped after about 6o-70 6500rpm nitrous dropps on slicks. My only problem was when i removed the trans to installed an auto. The clutch disc did look alittle worn. But it still felt the same as always,great.
Spec 5 requires no break in, it is a sintered iron disk. I love the Spec 5. I ran a Spec 2 for 40,000 miles. It is absolutely imperative with Spec's that you have a machine shop balance both the flywheel and pressure plate.

.... some people have good luck with spec but most stories i have herd were bad... i will never own a spec!

...Sorry to break it to you, but you have either picked the wrong hobby (high-performance modified cars) or you need to purchase a GM clutch if you want there to be absolutely no evidence of a high-performance aftermarket clutch in there.

sorry for the hijack...
