A few basic modification questions
 
Well, since my clutch is shot and I have to replace it, its got me thinking.

Since I'm down there anyway, should I replace the flywheel as well? NOTE: I do not know the condition of the flywheel, but there are no outward indicators that it is bad, just my slipping clutch.

I am not looking to turn my car into a mega-performance machine (yet), just make my daily driver a little more fun. I also think intake and exhaust modifications would be in order, with a rebuild not too far down the road (thats the light from the freight train at the end of the tunnel: 150K miles, tick-tock).

Given the above goal statement, would replacing the flywheel be a worthywhile (large) expendature? If so, who makes good flywheels, and how light should I be looking at?

I just bought a ACT clutch setup, Heavy Duty pressure plate, organic full-face disc. Should I have given more consideration to a 6-puck disc? How are the ACT flywheels?

Thanks

well replacing your flywheel is whether or not you like a quick response to revs! If you road race your car then worth while all the way if you drag then no! but if you are driving it on the street I would suggest that you simply get the flywheel resurfaced before you put a new clutch in!

Here's my thinking:

I gotta go through all the steps to replace the clutch anyway, which includes removing the flywheel for resurfacing. So while I am under there, if a flywheel would be appropriate, why not?

I am interested in the acceleration benefits that I understand result from a lighter flywheel. And if I combine this with a new intake and exhaust in the near future and a rebuild in the far future, then my car will be a little more "spirited".

A lighter flywheel is definitely recommended. :)

yes the car will be "spirited" with a light weight flywhell, It revs faster and there is less rotating mass so at high rev shifts the rpms drop faster making it a little bit easyer on the tranny but not much! I would think if you want a spirited ride you would look at doing the light weight flywheel a good beefy sprung hub clutch and light weight flywheel, but instead of the exhaust (assuming the one you have on there is good) I would do the suspension that is what I would concder a "spirited ride"

yeah you need to ship that back and get the 6 puck with a light weight flywheel. I bought the same ss clutch you have and left the stock flywheel and I regret it. My friend has the 9lb flywheel and 6 puck and the cool factor is a 10. I am getting a hybrid t2 motor build and when it goes in the car it will have these toys on it.

I disagree DO NOT get a clutch with an unsprung center! There is consequences to this, this clutch was desinged for high reving track cars. not street cars. You will litterally rattle your car appart with a six puck unsprung clutch! besides you can get just as much clamping power out of a sprung center clutch as you can a unsprung.

Yea, I don't think I want an unsprung clutch disc. From what I have read, that is way beyond my needs. I am not even sure if I want a 6-puck disc. I have never driven anything but a full-face disc. Are 6-puck discs hard to drive in stop and go traffic?

Well said jreynish, a racing clutch will shake the heck outta you and your car unless you plan to floor it everytime. Its a clutch for more extreme full throttle racing, get a street clutch. Your fine with your HD clutch you got now. Getting a lightweight flywheel will help you alot, just be prepared to lose some of your low end.
