Default Spec Stage 2...With this combo?

Pacesetter LT's Headers
ORY
Some catback exhaust, maybe Borla
Cutout
SLP Air Lid


Since my Stage 1 is slipping Im thinking of upgrading to a Stage 2 but I want to get your opinions on it before I buy my clutch. This will be my daily driver and I dont think any major mods are going to happen, basically I'll probably ONLY do bolt ons for a while.

I had a Spec 2 for 40,000 miles. It was a great clutch., many 4,000 rpm dumps. Make sure you get it balanced before the install. I replaced it with a Spec 5.

I have a SPEC stage 2 clutch in my 2000 Trans Am right now. I like it. However if u get it make sure to break it in properly for at LEAST 500 miles. Ive had mine for about 2500 miles now and it is great. many high rpm dumps. The only problem (which seems to be getting better with miles) is that there is a little bit of vibration at low rpm starts. at about 1100 rpm theres a slight vibration. perhaps it needs to be balanced, im not sure. other than that, the clutch is great.

Before I had my Spec 2 balanced it's max vibration was at 1,100 rpm, gone by 1,800 rpm. Do yourself a favor and get it balanced.

You take the flywheel and pressure plate to a local machine shop and they will zero balance the flywheel first, and then balance the PP bolted to the flywheel. The end result is no vibration.

Hmm... Should most any machine shop be able to do this? I can see taking it to one and they saying, "Huh?"

This is unbelievable!
It's apparently common to buy a clutch (A NEW CLUTCH) and send it out for balancing.
Sounds like a joke... like buy a new car and send it to a shop for a complete check and overhaul.
Someone is fuc... with us big time, and we keep buying their crap.
unbelievable.

Look at it this way, any machine shop that can't balance a clutch isn't much of a machine shop. Better shops use a Heintz[sp] machine. I just had a Spec 5 balanced a few months ago the owner of the shop I go to said it was only out a few grams, which he balanced out. The owner also told me you couldn't believe how out of balance some of the clutches he gets are. He said that some clutches are extremely difficult if not impossible to balance correctly, because as the clutch spins up the balance changes as parts in the PP move.

Oh, Lord... I can see myself going to about 10 shops and none of them knowing what I'm talking about. Then, the one that does take it will do nothing and charge me $100. Then, I'll complain about shuttering and tell the whole wolrd, "I had it balanced!"

I really don't know what the point is that you're trying to make. All that I'm trying to say is that many or most clutches being marketed today need some fine tuning. By the way balancing applies to cranks, rods and other performance parts. I hope that's not to difficult to understand.
