Clutch questions

I want to replace the clutch that i have in my car. It has a T-5. I've been looking at Centerforce clutches. I'm not very familiar with the differences with clutches. I was told by a friend that the Centerforce was the nicest clutch to get. Now my question is, is what is the difference between the Centerforce I and Centerforce II. Also what is dual friction? Dual clutches? Could i use that would i have to modify the transmission for the dual friction? And lastly what else should be replaced with the clutch? T.O. Bearing?, Pressure Plate?, etc... I'm not to familiar with the workings of a transmission but im a quick learner so if any of you have any advice/answers to my questions i would greatly appreciate it.

Thanks

well the differant levels have to do with there holding power, I would read each one very well I know some real high perfomance clutches req. the use of a differant flywheel due to the cast factory ones comming apart under sever conditions, I think the t-5 whould fail first but, like I said they all have ratings and suggestions for there use. I heard both good and bad about center-force but, never used one. they always looked way too $$$ for me but would have tried one if I had the extra cash at the time.

the centerforce II dual friction is the highest holding power.....you can use it with your stock flywheel, but it might be a good idea to have the flywheel resurfaced.

the clutch kit comes with the clutch disc, and the pressure plate, and a new throwout bearing.

my car is making over 400hp at the wheels and i have that clutch...its survived 2 years so far and has never slipped....about 10,000 miles, and 50+ passes at the track

From what centerforce says the Centerforce I has 30% more holding power the Centerforce II has 60% more holding power and the dual friction has 90% more holding power. Now would i have to get the flywheel resurfaced/replaced with all of these clutches or just the Centerforce II and the dual friction?

You should get the flywheel resurfaced no matter what clutch you put in. Unless of course you enjoy working on it so much that you'd like to take apart a second time to get that done when you get tired of it still not working right.

Put in a new throwout bearing and a new pilot bushing or bearing while you're there; and replace the clutch fork if it shows any visible wear at all on the tips of it where it presses on the throwout bearing.

I'd recommend the CF DF clutch. I've had just about every kind of clutch there is at one time or another, and this is the best one I've ever had, as far as a combination of smooth operation, hard hookup when I want it, and long life.

The DF thing is that it has 2 different types of friction material on the 2 sides of it.

another thing with a centerforce clutch.....

the break in period is critical, there are alot of people who claim that these clutches are worthless and wont last,

this is usually because they didnt break them in properly.....your supposed to drive the car normally for about 500 miles without any hard acceleration or abuse in order to properly seat the clutch disc on the flywheel and pressure plate......do this right, and it will never give you a problem
