Clutch Masters FX200?
 
Does anyone actually have one?

Every thread related to CM, it seems people are getting the FX300. That's fine, and I'm sure it's a great clutch, but I want a full-face disc and wanted to hear reviews/setups of people who had gone with the FX200.

The 200 seems to be a better choice for a car more seriously daily driven (traffic, lots of stop-and-go, etc), but I haven't found any LGT reviews of it.

Until convinced otherwise, I'll be going with the old ACT HDSS standby, and I'll probably use my OEM single mass flywheel, after having it machined.

Get the FX300. :hide:

Seriously, it is lighter and easier to drive in traffic than stock.

But the 300 isn't a full face. I was just looking for FX200 reviews.

I'll probably just go with ACT, then.

I don't know enough about clutches to appreciate the advantage of full face? Is it a longer use life?

BAC5.2 05-13-2011 07:27 AM

It has to do with engagement.

For a given force, pressure is inversely proportional to area. A decrease in area, means an increase in pressure.

So full-face clutches are more easily modulated than puck/pad style clutches. But they can't hold as much power.

I want a full-face, because I don't race the car and I don't intend to. I won't be making more than 300whp with a 5-speed still in it, and I won't be launching it either. Puck/pad clutches are also typically noisier than full-face clutches, and this isn't a race car.

Full face clutches also have more surface area, so they heat up less readily and have more material so they wear less quickly.

I had an unsprung 4-puck in my old car. It was easy enough to drive every day, but it was just too aggressive and unforgiving for a relaxing "GT" type car.

The FX200 intrigues me, because of the carbon kevlar face material. The wear life on kevlar based materials is typically astronomical as long as they don't overheat. Once overheated and glazed, they don't tend to return back to their original state like an organic full-carbon based clutch will (where you can "wear off" the glaze).

Thanks and good luck.

Not trying to sell you on the FX300 but IMO, it is much smoother than stock, easier to modulate and drive smoothly than stock and there was no noise increase that I noticed.

I have only had it for 700 miles so I am still in the honeymoon period..so I can't comment on longevety and/or glazing issues. I also never launch it or beat on it..i just thought the extra holding power (along with zero drivability issues) made the 300 a better choice for me.

As you probably already know, the ACT are known to be noisy (that's what scared me away from it) but they do have a proven track record.

go ACT and be done with it.

BAC5.2 05-13-2011 09:31 AM

B - I appreciate the review.

Mustang - I'm thinking that's probably the way I'll go. I was just curious if anyone was actually using the FX200 (or the 100, I guess).

This was from fredbeansparts.com:

The Clutch Masters FX300 clutch utilizes a full face clutch with segments of Kevlar to provide more holding power than a FX100 or FX200, yet still offer exceptionally smooth driveability and long life.

According to them the FX300 is a full face clutch.

BAC5.2 05-13-2011 10:06 AM

That's not an accurate description. According to Clutchmasters:

Quote:

The FX300 System uses the Power Plus I Pressure Plate with a Steel Back Segmented Kevlar disc.
Even looking at the pictures, you can tell it's not a full face.

Even with the LWFW, i find the fx300 just as easy to modulate as stock, and has no noise. It's not an on/off puck style clutch.

But if you're sure you won't go more than 300whp, I can see the fx200 being a good choice. That would be my choice if i stayed with stage 2 and needed a regular replacement.

BAC5.2 05-13-2011 10:18 AM

I definitely won't be using a LWFW, but it's good to hear about the drivability of the -300. Maybe I'll find someone with one local and go for a spin. If it's not too hateful I might just go with it instead.

It really seems like the 300 is just a pad version of the 200, with the same pressure plate and everything.

:lol:I had a 3 puck unsprung and it was basically undriveable in traffic:lol:
(not in a subaru, in a drag car I drove around all stupid like)

I doubt there will be much difference in pedal feel, engagement or longevity for your purpose but I am interested to see what you end up doing.

Still haven't found any reviews of the FX200.

It's like no one buys it, but no one can say why. They just arbitrarily go with the FX300.

I wonder if the FX300 actually has a softer pressure plate than the FX200, and takes advantage of the decrease in surface area to improve power capacity. They remove clutch disc material to make up for the light pressure plate, and still get the same clamping force.

But, of course, that's unsubstantiated. I haven't yet found anyone who has put any miles on an FX200. And most of the FX300 reviews I've seen have fewer than 10k on them, no test-of-time in my book.

Time to call Clutch Masters.

Come test out my Fx300. I also have nothing but good things to say about it.
