Why?

It took me a little over an hour (rusty bolts) to pull my transmission. half an hour to do the rear main and put the clutch in and about another hour to button everything back up again.

This is not targeted at FM. The point I am making is the ACT costs more than clutchnet, FM, Chinaclutch, whatever, but you put it in once and you are done. Read all the clutch threads and make your own decision. I did.

I've driven an ACT clutch-equipped Miata extensively, so all the threads in the world won't make me any better informed. Personally, I don't want to build up my left leg muscles quite that much. Unlike the ACT piece, the FM clutch doesn't engage 2 mm off the floor boards and doesn't feel like a Nautilus machine. I'm glad they took the time to develop something more drivable than your "gold standard".

This is only my opinion, of course, but my comments will become something for people to consider when they peruse all the clutch threads extant.

I think anyone who thinks the ACT XT takes too much force to actuate and engages too soon needs to hit the gym and learn how to adjust a clutch. I have an ACT XT in a DD and it is fine. Seriously, I still do not get what all the whining is about clutch pedal force. Would you like some cheese with that?

Fact is, both Clutchnet and FM clutches have had problems. Per the OP, if he wants to do the clutch once and be done with it, IMO, ACT is the way to go.

I'm in on this thread, i will be buying a clutch and hopefully soon a 6 speed, I ran an xtd 6 puck for a while, before i nuked my first trans, i figured out i could chirp 3rd and was a ricer. That contributed to trans failure.

What problems have you heard of with the FM clutch?

Wow Tex, you sure wield a mean cliché. No more, please - my ego will collapse in on itself completely. Members, I retract all my previous comments. The hot tip is to buy an ACT clutch along with a gym membership. Or, if you have a trick knee, swap in an automatic transmission.

There was a manufacturer's error that made the pressure plate fingers slightly too short, which could allow the release bearing to fall through the center of the fingers when the clutch is fully depressed. The fault was found, a new pressure plate has since been produced and it, along with an updated release bearing, was sent out to existing Level 2 customers.

Thus, the problem no longer exists for Level 2 clutches, and never existed for Level 1 clutches (which is the model you should choose, unless you run ludicrous power levels).

Ok that makes sense. I had heard that there was some sort of a problem with the level 2, but they had fixed it. I had just never seen what it actually was.

Canada? I thought FM was in Colorado.

The U.S. is Canada's largest trading partner. I take advantage of that fact from time to time to buy parts I need.

ZX-Tex 05-01-2010 04:34 PM

Oh really? I did not know Canada was the biggest trading partner of the U.S.. Thank you very much for that fact which has forever changed my perception of Canadians like you. Up until this point in this thread I was beginning to doubt their worth.

My recommendation is still ACT in case the OP was wondering.

DeerHunter 05-01-2010 04:50 PM

While that's not exactly what I said, it is actually a reciprocal relationship (http://www.census.gov/foreign-trade/...p/top0612.html). Thanks for the validation though. We Canadians are forever grateful for your country's collective forebearance in allowing us to exist :facepalm:

250 hp buy a cheap ebay stage 3 clutch and drive on.

BTW your interpretation of that comment was incorrect.

Well you live in Texas, so you would think that. :makeout:

I'm going to do an FM s2 with the 949 F1 clutch next. Its light, cheap, and supposedly holds.

My sincere apologies. Without an emoticon, I had absolutely no idea of your intention. Can't blame me for misunderstanding when most people south of our border can't even locate Canada on a map.

Lack of Vitamin D due to our northern climes has atrophied my brain, so could you please tell me what "Canada? I thought FM was in Colorado" was supposed to mean? I thought I was the master of the obscure comment, but I may have met my match :bowdown:

falcon 05-02-2010 01:43 AM

I agree. After many, many trips to the US, I still can't fathom how so many people living in WA, OR, and Cali don't know where "British Columbia" is. Like, come on... really? I can point out every US State on a map with ease. I guess I can thank our education system for that.


But... uh, back on subject. My centerforce is good for 260wtq.

I have an XTSS, the pedal force is about the same as required by the stock clutch on my WRX. Perfectly fine for daily driving.

As for where the pedal engages/disengages the clutch, any fool with a Haynes manual and a couple of wrenches can adjust that in about three minutes.

Mikelly 05-02-2010 09:18 AM

Jeebus...

OK, let's rewind...

Someone early on asked why I didn't search. We did. We're pretty well versed in what FM has for this application, but wanted to see what "other" stuff is out there... I have an ACT clutch in the spec miata we're developing, so I'm aware of their product...

Some of you guys want to piss and moan like children for the sake of pissin' and moaning like children. For those of us who are just seeking relevent and pertinent info, please park the "'tudes" and just provide the info... You can spar with your buddies in PM, no really...

Mike
