So far, so good! The guys at FFTEC seemed to do an excellent install of the clutch. I was expecting this to be an extremely difficult clutch to contend with compared to stock, but I was completely wrong. The pedal doesn't feel any heavier, either. Everything feels absolutely smooth. The clutch grabs well and I will continue to drive the car gently in stop/go traffic for 500 miles or so. I am about 110 miles in after a couple of days. No complaints yet. Even chatter has been minimal. The stock clutch on my 540i chatters a lot more.

The real test, I suppose, will be what happens when I run the full E85 tune and floor it. For now, it's several tanks of 91 and driving passively in traffic.

Good review.

These Spec clutches appear to drive very fair for the power they hold and have a good life expectancy compared to other options.

But I digress, if there is one thing about clutch kits people should realize is any aftermarket choice is a gamble.

If you are willing to make the power then you need to be willing to sacrifice on some aspect of aftermarket clutches. We got a bunch of guys with basically tune only cars, full bolt ons, and some single turbo guys that are extremely happy with these clutches. Not to mention a good portion who now have the Spec Clutches originally had the ACT and were not happy with it at all. Either the low engagement point and or the longevity of the clutch steered them away from a 2nd purchase.

If anyone has any questions, let me know.

We have a very nice FAQ in our clutch section for the BMW 135i 335i about Spec Clutches and how to choose the best one for you.

In a nut shell if you plan on making over 500WHP we suggest the single mass steel flywheel, as the OEM DMFW has been causing misfires due to an imbalance at high HP.

Otherwise we recommend anyone in the regular bolt on territory to stick with the OEM DMFW, and we highly recommend a new one as resurfacing them improperly will cause problems and not many shops can actually do it right.

The aluminum flywheel chatters more then the steel flywheel single mass options. Our FAQ also mentions in detail what comes with each specific clutch kit. I'd post a link but we are not allowed to here.

Hey Jeff what does people mean when they say "machined dmfw" ???
Is it stock flywheel or what???

[flexinator]

They mean, resurfaced so it can be reused. Most people buy a new one. Higher power applications seem to use steel smfw.

Correct. I would avoid getting the DMFW resurfaced as I've had some customers experience problems shortly after as they were not machined properly.

For those looking for an OEM DMFW replacement google "Luk Dual Mass Flywheel BMW 335i". It's much cheaper then getting one from the dealer.

Otherwise for guys with over 500WHP + you NEED a single mass flywheel from spec. Steel is preferred as it has less chatter.

Thank you very much Jeff!!!

A friend of mine went through with the install but he had the stage 3 and it chatters quite a bit when he matted it with the SMFW.

It spools/revs up quicker, but make a lot more noise then running a DMFW. To each their own I guess to me it sounded like bad WG rattle lol

I just installed stg3+/mfactrory steel smfw, bumped idle up to 850 for now and chatter noise (1-10) it is about a 2 at most, i am also fully catless/exhaust though. Basically i notice NO noise difference compared to oem stock clutch/dmfw so far. If i bump idle up to 900 (golden number), i am sure i will hear zero chatter. Sychromax Trans Fluid.

Was that the 3 or the 3+, people throw around 3 sometimes when they mean 3+.

3+ is full face where as 3 is 6 puck.

Eitherway, as Lshaw said, idle bump helps or even the fluid used can reduce some noise also.

At the end of the day, if you don't need the SMFW, I'd personally stick with a new DMFW.

Was a 3 because was just a step up from mine when I got the 2+

It's all about preference in the end, but since I use my car for professional/business use as well I don't want clients hearing funny noises haha

I'm the same way in my personal car, regardless. It's why I didn't even do catless downpipes this time on my second E92.

The 3 won't drive has good as the 3+ but most of those noises is the SMFW as you know.

Like I said, stick with a fresh DMFW when you can. If you know you are going big single are upgraded twins with E85, then the DMFW may not be able to cope as they become imbalanced, especially with age.

So I am about 1k miles in on my stg3+/smfw. How high is everybody's engagement point. During break-in, and currently, my engagement point is about 1/8 of pedal travel (opposite of floor), relatively high. Ive always been used to heavy low engagement point clutches as I can shift quickly by flooring the clutch and releasing, but the high engagement point is growing on me, I can shift just as fast, with minimal effort.



Is this normal for spec clutches? Just curious, as there is so much excess pedal travel now and basically nullifies clutch stop, as I don't the engagement point is no where near the floor.

Curious on more feedback too.

My daily is currently my x5

Will update my thread on performance in warmer weather in a few weeks. Also curious to see how loud the "rattle" noise (gear noise)..... as once was referred to as "chatter," while AC is on.

...for the record, using the term chatter synonymously with rattle when describing gear noise i feel is pretty suffice. I mean, if you are complaining/talking about the actual clutch world term of chatter, you obviously are not properly using the clutch. Coming from a 6 puck stg 3 exedy on my subaru, trust mee i knowwwww

You know how it is, it's hard to please everyone but yea chatter/rattle, it's noise!

A 6 puck clutch is for the birds!

I would not bother with the aluminum as it chatters like crazy. Go with the steel if you have too. Otherwise go with the OEM DMFW if you are just bolt ons to reduce all chances of chattering.

Is there any chance that a DMFW would be designed to handle more than the 500hp?

I am running my car with upgraded turbos and are one of them that is limited to more boost due to the misfire problem.
I do not want to change to a SMFW as it makes to much noice for my tast after all it is my daily driver.
