Hi there,

I bought a vrs with smf and it chatters when being driven at low revs in first gear with my foot off the clutch.

I know it's normal to get chatter when idling stationary but how about when slowly moving in first?

My mates SMF is noisiest when moving slowly and can't really hear it in idle.

Yerp that's normal.

Have heard this too.

Strange because my SMF is totally quiet even on idle.Press clutch down nothing.Let clutch up nothing.Really smooth responsive drive.

Mine rattles like a mother dude. Nothing to worry about. Mainly below 10k you'll here it.

So glad I listened to the garage and didn't go for an SMF...

Yep mine does the same

Mine is noisy at tick over, and at slow speeds - especially around town

Yup, mine is also clatter-tastic. I really don't mind it. It can be quite amusing at traffic lights when people look over, expectantly waiting for your car to fall apart.

Thanks for the replies - very reassuring.

I meant below 1500 lol. Just sit at lights and pop in neutral then lift off the clutch. Everyone thinks exhaust is about to drop off. Or ya take it to the garage and the mechanics tell you somethings wrong with the car......nope its a bag of nails

Surely all these vibrations can't be good for the car?

They are, afterall, fitted with a DMF for a reason - to protect the gearbox and drive train from the torque spikes and vibrations from the engine.

Anyway. Each to their own... the noise would drive me insane! lol

It does protect to a degree, but for mapped cars smf is essential as it kills the dmf quickly. Mine is silent and feels normal. Im sure its down to the weight of the flywheel, mine is a like for like kg match and is silent - others i know of have light race variety and clatter like hell

There is no need for a smf until your really going for top figure on a hybrid turbo, and even then it's debatable. Standard/mapped/sensible mapped hybrids will be fine with a stock dmf.

I went for a lighter smf for the fast revving you gain from not lugging the weight of a dmf round, using that power to move the car instead. The lighter the smf the more noticeable the gains are. Personally I'm not a fan of these "silent" smf's, no performance gain so might as well stick with the dmf. If as I said earlier your going for big figures and need a smf for reliability then you'll be wanting a light one anyway to extract as much as possible from your set up,

Just my thoughts on them.

makes sense to me mate. However dmf's are inherently unreliable. fact! An smf will never ever fail so the cost of replacing a dmf (which is massive) especially when clutch s nowhere near on its way out seems a shame and rather pointless too.

Mine went and my clutch was still in fine fettle, may never had needed changed in the time i had the car. So in my opinion if you HAVE to change your flywheel, and dont want the chatter do it with a silent SMF because 1: cheaper 2: more reliable 3: Still more responsive 4: lifetime guarantee.

I know alot who have mapped the car and dmf has failed within a month. Thats why alot on here would advocate getting it converted with a map.

wasnt there an SMF kit which was 'claimed' to be silent?

yes

yes

Which one?

I have the Valeo kit, and it's pretty quiet. It took a while to bed in though. If I'm cruising very gently in first (i.e. when I'm picking up schoolgirls off the pavement) then it does chatter a bit, but the responsiveness you get over the DMF more than evens it out.
