Clutch Opinions

**Halon** · 05-03-2009

I'm currently running a Fidanza 4.3 clutch. It's a sprung 6-puck that claims to be able to hold somewhere around 650ish tq. It's holding my power real well, like on a 4th gear pull. No slippage.

But today was when I really started launching with this clutch, and it did not perform anywhere near what I would have hoped. Just the slightest slipping of it on a launch, and it slips through all gears for the entire run. It can hold tons of power, but if it can't take a launch then it's not much good to me.

So here I am now, looking for a new clutch, and open to hear what anyone has to say.

I'm looking at 4 or 6 puck ACT 2600's, 2900's, Competition stage 5, Clutch Master stage 5.

Keep in mind, that I do NOT want to go with a twin disk, so don't go there.

I'm thinking about going with a non-sprung hub. It may be a little bit rougher on the street, but I think the lack of a sprung hub may help avoid slipping it off the line, which should hopefully reduce the chances of me running into the issue I am.

What clutch was Shane running when he ran his 10?

My vote goes for the Comp Stage 5, or the Fidanza 5.4 if you want a solid hub.

I would go 2900, 3200, or Twin disk at your level, imo

**Halon** · 05-03-2009

I typically try to avoid ACT. Just haven't been all that happy with them in the past. But I may call them and ask them about their 2900 PP. I heard a couple people mention something about them having a new design on the 2900PP that allows for a lighter clutch pedal.

Twin disk is still something I'm really not interested in going with at this point in time.

Also that Fidanza 5.4 is a sintered iron disk. I've never felt one, but they sound harsh, so I'm a bit hesitant on that one.

**Kracka** · 05-03-2009

The 5.4 would definitely be rough on the drivetrain and not be much fun on the street.

I have the act 2900 with a sprung 6 puck and it seems to be fairly similar to the feel of a 2600 and holds good for what I have been able to put at it so far. Not too bad pedal pressure and drivability.

**Halon** · 05-03-2009

Right now I'm honestly leaning towards that, even though I told myself I was going to stay away from ACT.

Didn't they redesign their pressure plate and clutch disks lately tho that took care of previous problems?

I've been running the ACT 2600 with a 6 puck sprung disk for about 2 years. Been workin great for me. I say go for the 2900 with the 6 puck

95talonracer · 05-03-2009

I think the 2900 6 puck combo is rated at like 595 tq as well. If you want, you can drive my car to see if you like the combo.

4g63tcrazy · 05-03-2009

I know whatever the rating is of the PP add 100tq onto it if you get a pucked disk..

Speedfreak · 05-03-2009

I'm in the same boat as Brandon. My 2600/street disc slips at the strip, and slips in fifth on the highway at WOT. I have an old, but brand new 2900 I was considering until I just read you guys stating that they redesigned something or another.. Can you expand on that? Wondering if I should consider using or not. Was also considering just trying a 6 puck with the current 2600 PP.

I like my competition clutch stage 4. I have about 3k miles of very hard street driving on it and on trip to the track with 11 passes on it. Its held up great to the abuse and it was super cheap. Granted you make close to 100 tq/hp more than me I don't know if you can compare much, but I figured one more opinion never hurt.

TsiEagleTalon92 · 05-03-2009

I might be able to vouch for the lighter pedal on the 2900. I just got my car back together and it seems to me as if it has less force to put into it than my 2600 did.

The Comp Stage 4 or more or less equivalent to his Fidanza 4.3. Great clutch, but 2 years of use + Brandon's power was just too much for it I guess

Super Bleeder!! · 05-03-2009

Im going to ignore what you've said and say GET A TWIN!

Way back when shane ran his 10 i think he was running an AMS twindisc if memory serves.

Forgot about that, I think you are right.

But I agree with Brandon.. No wanty a twin.

The iron clutches are a bit tricky to drive on the street but if you get off it quickly you should have no welding problems. Unfortunately at the power level you are at, you will be pushing the limits on any single disc setup. You just don't have enough clutch diameter to harness the torque without having to give in pedal pressure (substantially) or longevity/driveability.

My opinion on sprung versus unsprung: If you drive it on the street more than the track, get sprung. If you drive it at the track more than the street, get unsprung. I've driven Jim's Evo on the street who had an unsprung clutch at the time and that was enough for me to decide that I'd never get an unsprung clutch for a street car.

It might be fine for you since yours is a weekend warrior, but at least drive such a car so you know what you'd be dealing with every time you sit in the seat if you haven't already.
