Spec stage 3 or FMS HD clutch

urban96 · Oct 18, 2006

well im about to install my alum flywheel and tremec goodies. my question is what clutch do you think i should use, spec or FMS.

spec: will hold a lot more power them im making but i hear it dosent have very good street manners

fms: not a bad clutch, ive liked it so far

BTW i have both clutches sitting in my garage right now but dont know what one to choose

my power is probably in the 280rwhp range and i dont plan on any serious mods anytime soon. maybe just some sticky tires

Motorsport HD.

Well, I got the Spec Stage 3. It took a little getting used to but now its no problem to drive around town and it really grabs.

DaveB · Oct 18, 2006

If I were looking at SPECs in that power range Id look at the Stage 1 or 2. Cheaper and will hold the power. I have a Stage 1 that has lasted through probably 80-100 quarter mile runs along with last season of drag radials. It wasnt till I tried power shifting that it started to grab high, still doesnt even slip. I've never had a Ford clutch so I cant comment on that.

from the experiences my friends and i have had with spec, i would throw(literaly) the spec as hard as you can at a brick wall--repeat until it is unusable.

I have heard SPEC 3's are great.... how ever SPEC 2's chatter like holy hell

You couldn't give me a spec clutch. I share Bimmer's thoughts on it. I'd stick the FMS HD for the time being, it should be fine in a coupe with your power levels.

get a new one, CENTERFORCE

parchisi · Oct 19, 2006

Why you all be hatin' on Spec? I've heard they're tough as hell and from my experience with almost 4k, driveability isn't too bad except for some chatter when I really slip it.

Green 94 5.0 · Oct 19, 2006

everybody complains about driveability, but the first time i drove joes car with the blower all was well. the second time i drove it after the 347 it chattered every now and then. if i hadnt gone with pro motion, i probably would have gone with the spec 3.

Adam95GT · Oct 19, 2006

yea the only problems ive heard of was chatter... and i think my friend might of had a spec 4 puck style that snapped a puck clear off and imbedded it in to his tranny of his h22'd hatch... im not sure if it was a spec though..

I have heard this too and wouldn't have every bought specifically a SPEC. However, I recently bought Dream94GT's car and it has a SPEC 2 on it and it has zero chatter and it isn't too on/off either. I still prefer centerforce d/f, but this has changed my views on SPEC a little anyway.

I have a mcleud clutch stage 2 its awsome good pedal feel and great grip friendly for daily drivers too

5spd GT · Oct 19, 2006

The motorsport HD will have a heavy pedal.

It will suit the power you have just fine...

S351Saleen77 · Oct 20, 2006

I have 1kmi on a spec stage 3 and the street manners on mine are not good. SPEC said the clutch would get better after 500mi, it did but it is very "grabby". I am looking at getting something different. Mabye with more miles it would get better?

Right now I have 650rwhp so with the amount you are making I would never go with a stage 3 spec, I would use a King Cobra or a King Cobra pressure plate and a centerforce disc if you want more holding. I hate the standard FMS clutch, the King Cobra has much better pedal feel for $30 more.

At www.buyfordracing.com it isn't even that big of a difference.

I agree, the King Cobra is a much better clutch, since I have drove on both...(HD and KC)

BlownFiveLiter · Oct 21, 2006

I have no experience with the Spec clutches, but I've run the King Cobra once before, and just installed one when I dropped in my new engine. I'm very pleased with the overall feel of the clutch, and even though it's not broken in yet, it's never chattered, since the first time I've driven the car.
