SMF is soild metal so cannot in therory break but rattle when installed in your clutch/gearbox.
DMF is two metal discs held together with springs which remove the vibration from the gearbox and shift mechanism. Since diesel cars produce a lot of torque the DMF has been known to pull itself apart, you can tell when this is happening as you will get a vibration in the car since the DMF is no longer doing it`s job of removing the vibration. Millions of cars are fitted with DMF`s some of which break like any other car component, trouble is you only hear about the ones that break not the other 99.9% of the millions of cars that don`t get a problem with the DMF.

Correct. Personally i wouldn`t even think about it unless you are running 230+ bhp and 360 + lb torque then i still wouldn`t bother. Running 330bhp and 440lb torque on my car and no DMF problems.

Cheers for the PM gylnnd.

Just spoke to Dave @ DSB. Seems a proper decent bloke! He has beaten the price for a DMF & Labour hands down but doesnt have a price for the performance sachs clutch as he doesn't seem to fit non-oem parts.

So buying the clutch from somewhere like JBS, Awesome etc would take the price to £911 inc VAT/Fitting.

Roughly £75 saving from JBS doing the whole lot - which is a saving, just a shame I can't find a supplier that would sell me a performance sachs clutch for a lower price.

just had a throught, should i get a new DMF to get fitted as the car has done just short of 40k?

This is my dilema at the mo. All I can go by is if JBS tell me to change it or not - after they have taken off clutch and can see the flywheels condition.

Anyone know if flywheels wear? Or is it just a case of they become wobbly and need replacing?

I've also been told by a motor enthusiast who I deal with at work to change the flywheel even if it 'looks' ok - He says he has seen more than enough flywheels fail straight after a new or stronger clutch installed. Not sure if this is becasuse they have not 'bedded' in together.????.

I dont know enough a about transmssions to know what is going on.

No I didnt get the dmf and took a chance on the original being ok. If it wasn't I figured I could always order one for the next day from a dealer. I did order a new release bearing with the kit though which I think jabbasport offer anyway for £40ish.

Went out last night and clutch doesn't slip anymore :shrug:

Don't understand........

Mine feels like it slips slightly in very wet weather, give it a big boot in top at <2000rpm when it's been pissing down and the revs climb 500-1000rpm instantly with not much acceleration.

Do the same thing when it's not so wet and all is fine.

Car is around 26500miles old now, all standard but healthy nonetheless....;)

Mine started slipping on the way home from Bell Auto's lol

Kept it for another few k miles or so, then got a Sachs racing clutch kit (supplied & fitted) from JBS - offer on at the time for £675.16 (usual price is £741.40).

Good news is that after the new clutch was fitted, I got Pete to give me a lot more aggressive map - had it about 8 months now (33k on the clock), and it's running like a dream :)

ChrisUK - New flywheel too?

Can't wait for 2mrw to get the SACHS full kit fitted - I really miss the power @ 2k RPM now, just hope my flywheel is ok, clutch has only been slipping for a week and I'm not using the turbo power to save it slipping till its snorted.

Flywheel was OK, no need for a new one.

I was going to swap to a SMF, but was advised not to (why did SEAT put a DMF in there in the 1st place ?).

Fab job by the lads at JBS (get a shortshifter fitted at the same time FOC as they are right in there anyway putting your new clutch in !!)
