According to centerforce, the flywheel needs to be stepped to .004". The clutch I got is for the KA, but I assume the stepping applies to the CA flywheel as well. If you got this clutch, did you step your flywheel?

[originalsin]

i think your flywheel should always be stepped, but i dont think its a huge deal, idk mine isent stepped, im running that exact clutch and no probs, i ad a ***** of a time with getting the pressure plate on, had to take out all the pins and then ream the holes out slightly

No, not all clutch manufacturers require stepping. Some are flat, some need the flywheel to be cupped, and others to be stepped. I was just asking for this specific clutch as under the table on their site for the KA24DE, it requires stepping to .004"

i didn't step it either. i too had to remove all flywheel pins and drill out the holes an extra mm or two. been riding on for 1500 miles, so good so far.

I dont know about that. I test fit my friends CFDF and nothing had to be drilled out and I only had to remove 1 pin (it's a specific pin that needs to be removed, not just any pin).

I guess I will just try it out without stepping it. Wish I could get a definitive answer.

Chris, why not just have it stepped anyway? It doesn't cost hardly anything, and I don't see any reason why it would be stepped on the KA and not on the CA.

Of course, .004" is barely anything and I don't see how it would effect the performance of the clutch, but they built it and wouldn't have you do it for no reason at all.

Yeah, I am dropping it off today. I thought about it afterward.

[float_6969]

I'm excited to see what you think about it. I'm seriously contemplating the CFDF when I'm due for a new clutch, but I'm worried about it holding 280hp.

The only gripe people have about the CFDF is that it has an issue with lots of low-end torque (read: KA-T owners). As the clutch spins, the weights put more pressure on the disk. Since the CA makes the most torque up in the power band, I think it will work out pretty good.

yea i havent had any problems at all, and the pedal feel is great

Well, I dropped the flywheel off to get resurfaced and stepped. Cost me a whopping $38 out the door.

I had my flywheel stepped just like a KA when I used a KA clutch. My hks flywheel is also stepped I believe.

That was my thought exactly. When my my SPEC clutch was slipping last time (it was defective and SPEC rebuilt it for free) it wouldn't ever slip before about 3K. I figure that's enough revs that the weighs on the CF clutch would be putting some decent pressure on it.

The SPEC is still holding great, but I hate the pedal feel and the engagement point is too high.

itllbe easy with the engine out but doing it from under the car in a garage it was impossible to get them all in. drilling out 1-2mm made a huge difference

[c-rad]

Well, here is my freshly resurfaced and stepped flywheel-

Yeah, I am going to have that same issue. The way it is now, it will not bolt right onto the flywheel. The holes on the pressure plate need to be opened up a little bit towards the center.

For the people that got the KA CFDF clutch, why didnt you just get the CFDF clutch made for the CA? Thats the one I'm running but after a year of hard drifting I'm looking for something that can handle a little more power. Oh yeah Float_6969 what model spec clutch do you have? and do you have an aftermarket flywheel?

Its not in their catalog, or else i would have

[originalsin]

where these CA ones @?!?

[float_6969]

AFAIK Centerforce doesn't make a CA specific clutch. LINK?

SPEC Stage III clutch with a JUN lightweight flywheel (11lbs.)

[sideways danny]

RPS make a CA specific clutch organic and rated to 475 ft lbs or paddle and rated to 510ft lbs
