Why are people recommending FM stage 2 clutch when they are meant for over 300whp? Wouldn't it be be unnecessary heavy clutch pedal for his power level?
(I am asking because I am doing a build very close to the OP's and just ordered a FM stage 1 happy meal... Do I need to change to the stage 2 happy meal?)

pedal feels stock and can handle almost anything you throw at it.


turn down the disrepect and stop questioning us.

I don't mean to disrespect anyone.
I was wondering because I have ordered the stage 1 FM happy meal for my car that I am building with the similar power goals as the op.

Since people were recommending the stage 2 clutch, I was thinking maybe there was something wrong with the stage 1 clutch from FM that I can not seem to bring up by searching.

I was just going by what fm said on their site about stage 2 being

...for "Serious HP" cars only. Pedal effort is substantial, so if you don`t have 300 hp or more...
So the recommendation is that I should change my order from FM level 1 to FM level 2 happy meal?

Thank you for answering my noob questions...

if you really don't plan to exceed the 275whp the stg1 should be ok
if later you get the itch for more, and most do, then it won't hold up too long above that.

so basically yes and no

Stg1 is fine. But driving both, I wouldn't call the FM2 effort substantial, I'd call it a little heavier. the ACT XT was substantial, the Clutchnet Dual-Diaphragm Stg3 was SUBSTANTIAL, the FM2...hardly noticed.

Pedal pressure on the FM level 2 clutch is not bad at all anyone who thinks that is a heavy clutch pedal has never driven a cobra mustang.

Braineack 03-12-2013 05:35 PM

hell, even a Mustang GT.

I DD with an FM2 clutch and I don't even mind it in heavy traffic. It is heavier than stock but you get use to it in no time and I think it has better feel to it, as in the point of engagement is much easier to feel in the pedal.

Car is done and while the clutch is stiffer, it's totally doable and once you get some miles on it, gets easier. Car runs great too and just got tuned for 12psi on the stock turbo while I wait for my EFR manifold to arrive. The fun continues!

updates? I'm about to purchase a bunch of parts, and our builds are looking quite similar :D

Did you have problems with the main studs and the MBSP?

Yes, the machine shop cut the MBSP like so to fit them. They also de-burred the MBSP for me :)
