Wondering if anyone is running this clutch in their car. My toy is going to be 2.0 and 35r hence I'm looking for a clutch that I won't destroy quickly. The price on the CM is steep though.

I heard good things about south bend stage 5 as well. Looking for a totally streetable clutch that wont destroy my leg.

Mike, what clutch are you running on your car?

[SurferForever]

Might be a little pricey but somes with the flywheel as well...

Just put the short block in the car today, so I haven't driven on it yet. It has a rather interesting pedal feel, but it's not stiff at all. you can only press the clutch pedal half as far down as you can with a regular clutch, I think i need to install a rubber stopper behind it to prevent it from going all the way down (they say you may need to do that in the instructions) I'll update in a few days when I get the car running.

It's going to be noisey as hell when you press teh clutch pedal, because the floater plate isn't strapped.

also, this isnt the clutch if you are afraid of a light weight flywheel.

the flywheel weighs 6 lbs

the entire assembley weighs 15 lbs.

keep in mind that with a normal clutch, the pressure plate is rather heavy. this pressure plate weighs under a lb since its aluminum. the whole thing is probably half the weight of my old setup (9 lb flywheel, 6 puck & pressure plate)

Your old setup by your numbers equals 15 pounds. you jst said the who assembly weighs 15 pounds . . . im confused

hopefully my FX700 will be here for my Gti 1.8T, i'll test it out lol 35r + 40psi. Yes its expensive but i've seen evo tilton twin disks for 4500

I run a old WOA custom 4800 lbs dual diaphram 6 puck, but I plan on trying out the FX600 or FX700. If you want one let me know, I am offering them at a very low price and includes shipping.

CM claims it is 8 lbs(17 lbs entire assembly) for the Billet Aluminum flywheel. CM is making a Billet Steel flywheel for us that will be 14 lbs(23 lbs entire assembly), this will be an option that we will offer for a small price.

Your old setup by your numbers equals 15 pounds. you jst said the who assembly weighs 15 pounds . . . im confused

He said the FX600 total weight of twin plate and flywheel was 15 lbs, which was half of the weight(30 lbs total) of his old setup that used a very light weight 9 lbs flywheel. A standard clutch setup(pressure plate and disk) for our car is around 20-25 lbs, so add that to his 9 lbs flywheel and you end up with 29-34 lbs total.

You might be confused because you think he said 9 lbs flywheel plus 6 lbs disk, when in fact he said 6 "puck" which is the type of disk not the weight.

(correction) Just looked up one of my old orders for a stage 4 and 15 lbs flywheel, total weight for the box with both of them was right around 30 lbs. This puts the clutch kit right around 14-15 lbs.

Nice part about the twin plate setup is that not only is it lighter, the weight is much closer to the center since the clutch is much smaller in diameter.

You plan on running big slicks, because that is the only want you can compare a clutch setup on a FWD to one on a AWD.

My car is AWD

Oh. But you also list it about 700 lbs lighter then a A4.


BTW 40psi? That would put you way outside of the 35r flow map, well unless you plan on racing your car at 1000+ ft below sea level.


40psi at sea level has a PR of 3.7, the GT35r map shows a max of 3.3 and thats right next to the surge line.

My car is about 2800 with me, I was just saying 40 It will be in the 30 range and go up until it stops making power. In a couple weeks the car should be running and i will let you know how everything works.

That is a big concern for me, saw that video floating around of someone launching their S4 only to have their entire bell housing shatter from the flywheel exploding.

Your car with you in it is even lighter then my A4 without me in it.

Thats cool. I have been running 32psi which seems to be the normal boost that most people run on the GT35r, I will be pushing it a little higher but will most likely not go above 35-36psi since thats right around the peak PR.

That was Mike Simpply from Wicked and it was the flywheel that all of the S4's have had problems with in the past. Mike also used anti-lag when launching his Twin GT setup.

The S4 also uses a 240mm setup which means the weight is shifted further away from the center of the flywheel.

[pac1085]

I just weighed my old clutch parts (pressure plate + clutch disc) and they weighed about 12 lbs. My old flywheel was ~10 lbs. This setup will be 6-7 lbs lighter (w/ aluminum flywheel) than a 9 lb LWFW with a normal clutch, to put it in perspective.

Oh, another thing to keep in mind is that the discs are not sprung. There are some twin discs for other cars which are sprung, but this one is not.

Damn mike my car is still lighter. I still have the stock seats and no carbon fiber stuff yet. I would like 2500 but that might be pushing it.

I would really like to get a B5 A4 for a daily driver and have 500 on pump. If my car break too much times im done with it and going to the audi.

comparing orange to apple.


A street trim A4 1.8t at 2800 lbs isn't all that bad. There are plenty things I can do to get that weight down further, problem is that I wouldn't be able to run in the street class after that.

[djwimbo]

I'd love to have an A4 that weighed 2800lbs. Mine weighed in @ 3383lbs wet Friday, w/ my fat ass in it.

[pac1085]

Got about 86 miles on the clutch so far.

It is very annoying to drive in stop and go traffic - to be expected

It is loud when you press the clutch pedal in

It's noisy when engaging (maybe this will go away when it breaks in ,but you can hear the copper disc squealing)

grabs hard, and chatters a bit.

Overall it's not that bad but if you're looking for a clutch with great street manners this isnt for you.

I'll let you guys know if it changes a lot after break in.

[bob12312357]

I hope u weren't lookin for a DD stage 6 clutch 2 hold 500hp.lolz
I kid, I kid. That car is cool, what u do ot get the weight down so much.

[pac1085]

Got about 400 miles on this - don't buy the clutch if you plan on driving the car on the street much..that's all I gotta say!

[Don Supreme]

I wonder if the fx600 is any better??? I know I would never get the fx700 ---

Wait are you running the 600 or 700?

[pac1085]

I have the FX600, which is 1 kevlar disc and 1 copper disc. I couldn't imagine the FX700.

[Don Supreme]

dammit, that sucks....

I am already scared of what my clutch is going to do on the next track visit.

[pac1085]

It's not TERRIBLE, but it is hard to drive - harder than an unsprung 6 puck disc with LWFW. It would probably have been better with a steel flywheel (which is an option)

The kevlar disc is what slips when you let off the clutch, and then the copper disc just grabs - and grabs hard (makes a lot of noise too) I'm mostly concerned with wearing it out too fast.

It is an option now that we are having CM produce a steel flywheel for the twin plate, they didn't have one before.

[pac1085]

What I don't understand is this:

clutchmaster's website says that the FX600 comes with a PAIR of organic/kevlar discs.

the FX600 I recieved containted a kevlar disc (flywheel side) and a compressed ceramic bronze disc (like the fx700 uses) for the PP side.

When I bought it, I thought it was wrong, but when I called them they said no, that is correct.

Maybe they did that because it's AWD. I saw a FX600 on vwvortex which came with both kevlar discs.

Mike, what clutch are you running on your car?

It is going into two B6 A4s (2.0 stroker motors) and I think it will eventually be in Greg's car (400hpa4). I am entertaining the thought of one but we'll see how my SB OFE SS holds once I am re-tuned.

If you want one, talk to Mike and Greg.

Most likely done because of the AWD, the discription they give on their site is just for the kit which also covers FWD cars. I think all the dealers just copy that info and put it on their site, because if you use the pull down tabs on the CM web site to look up the FX600 for a A4 1.8t it says "kevlar mix" but doesnt say what it is mixed with.

[Pete@IE]

If you are doing a twin disk, I'd recommend trying to get a steel flywheel with it rather then the aluminum.

Most of the people we have talked to already want the billet steel, so now we are just waiting for CM to make it for us.

[fred2ka4]

I have a Clutch Master stage III kit, so I know it is not a comparison you are looking for but for everyday driving it is great and it has a very stock feel with just a slight hint of firmness. I have been running it now for about 2 1/2 years with no problems on a stock resurfaced flywheel.

Good call, its a lot less likely to pop on you. the weight doesn't hurt anyways. Nothing like a 2lb flywheel on top of already being a fairly small 4 cyl in a fairly big awd car to help it bog out of the hole and around town. Plus, a medium weight flywheel helps chill out the crank a bit.

Lots of people get caught up in "if light is good, a lot lighter must be better"- or looking at the setup on a formula atlantic and thinking that's what they need for their audi.

Yeah, but the A4 guys learned that lighter isn't better about 6 years ago, some people still order a 9 lbs flywheel but most end up going with the billet steel 15-16 lbs flywheels now since it is about 10 lbs lighter then stock but still has enough momentum so that the rpms dont drop too quickly.


With the CM twin plate setup, the difference between the aluminum and steel flywheel is about 6 lbs.

[Don Supreme]

How much longer before the steel wheels are ready? I need a new flywheel or clutch setup ASAP!

I asked greg and he is calling the rep, so once I know I will let you know.

[mike-2ptzero]

CM rep said the billet steel flywheel can be ready on weds.

How does the clutch feel fully broken in?
Perhaps it'll feel better with the steel flywheel instead.

I still feel the same way about it, I don't think a steel flywheel would help with the feel. I could see this clutch being a lot easier to drive on a fwd or rwd car, but not AWD. I try to avoid stop and go traffic like the plague now.

Is the clutch pretty much on/ off? Not a progressive feel?

[pac1085]

The first disc to grab is the kevlar one, which is slippable. But as soon as you let the clutch out past that and the copper disc grabs, it's instant. There's no slipping the copper disc. It's hard to explain.

Damn I wish you were closer to NYC, still really considering the clutch, it doesn't sound all too bad. A clutchmasters stage 4 feels pretty bad though, then again that clutch is pucked and it is fully ceramic.

Thanks for the input.
