    Want a remap and have the money but a few people have said that a remap will be on the limt of what a standard clutch in my 1.8 tqs (180bhp) can handle it's only done 60,000 but i don't want to gat a remap then have to spend big money on sorting a clutch and fly has anyone any first hand experience on this

    My std clutch lasted a few thousand miles once i was mapped, on my 2wd. I went from 142 to 199.

    my clutch slipped a fair bit just booting it on hill starts!! god knows how pants it would be on a remap!

    bare in mind the clutch is the weak link in system when you are 4WD. much more chance of slipping clutch than spinning all four wheels

    Any suggestions for a clutch upgrade for a 1.8tqs, 220bhp remap?

    solid flywheel to take 240mm clutch from s4 etc i think? Should be more than enough and you get rid of the naff std flywheel.

    that would be my choice.

    240mm solid flywheel and an off the shelf S4 clutch.

    Are these direct fit or does anything need modding and would a second hand fly be ok

    Siena does a bolt on solution. Its a special unit made to bolt onto the 1.8t as the std 240mm FW comes from a different bolt fitment IIRC

    If only this post had been around 2 months ago.... I replaced my 145K mile clutch on my QTS, it was near enuf down to the rivets, and wouldnt have lasted much more longer..... I kept (as I couldnt find a Std flywheel) the DMF causing the bill (trade) for the clutxh & FW to be a tad under £500 (not nice). I couldnt find the a std flywheel :(
    Still its REALLY soft and light now, you only need to breath on it... :)

    The clutch i first fitted was from the US it was a gripforce stage 3 paddle clutch. It gripped fine but i didn't like the bite. I was lucky and was offered a Southbend stage 3, that had the right bite and never let me down.

    When this one falls out I will hopefully have a Siena clutch here, IIRC its under £500 for the FW and clutch kit, but don't quote me....

    Some of the A3 guys use a corrado FW and vr6 plate or some combo like that

    I am about t0 install one of Sienna's 240mm flywheels with a Stage 3+ Southbend clutch.
    Dual mass is a waste of time for anyone running moderately increased power and they are far too expensive to justify,

    I currently run a Southbend stage 3 and it is as light as stock on the pedal but has never (and I mean never slipped). and I do drive it like I stole it on occasion.

    I import and distribute Southbend clutches in the Uk and they are Sachs hardware with refitted pressure plates and friction surfaces giving a range of higher pressure spring plates for higher torque applications and multi compound friction surfaces for better bite and longer lasting clutches.

    just check out the numerous 500bhp+ applications using them in the US on Vortex.

    They also do a stock size steel SMFW if you are not looking for nutty power or the cost.

    so what works out cheaper siena's clutch and fly or siena's clutch with a soutbend clutch, it will only have to handle 230bhp

    A stock S4 clutch will be more than adequate for 230hp, and i'd imagine they'll be much cheaper from the local motorfactors than a tasty southbend one.

    Siena charges around 250 iirc for the fly.

    A replacement DMF will be more than that without a doubt.

    close to double if not more.

    you will be fine with a SMFW and stock S4 clutch

    Jamie make sure if you use a LWFW you also get a sprung hub clutch.

    None. A Stock S4 flywheel is DMF, and it also wont fit your engine.

    Sienas flywheel is a custom unit designed to bolt to a 1.8T and take a 240mm S4 clutch.

    It costs approximately £250.

    A new DMF is at least 350 for an aftermarket one.

    I got my DMF (LUK - OE fit) for £250 + vat, the Clutch kit was another £150 + vat. Though euro car part had the clutch at £80, although I thought that was wrong so I ended gettting it from GSF. Dont forget the Flywheel mounting bolts though....and they are about £12 from a stealer......All cars these days are going DMF, cant think why though, all it does is do what the springs did in the centre of the clutch did and it was loads cheeper....

    Its smoother and reduces NVH from the drivetrain.

    Until it fails.

    But manufacturers dont really care about it failing, and lets face it, its a 10+year old car.

    Our cars DMF has packed up just last week, but the cars done 191k miles. Its not bad going for a component like that is it?

    I put a used stage 3 clutch on my 80k DMFW and it is fine. no slippage, no vibration. most situations the DMFW will be fine for another 50k

    I've been looking into alternative flywheels and it looks like the flywheel from an Audi 80, or very early A4 TDi is a single mass item, and can be coupled with the early A4 TDi to gain a clutch with a sprung centre that should bolt streight up.

    Marks interested too so i'm trying to get my hands on one so i can compare them.

    i'll find out how much it is to get the clutch changed then see if i have to try to find the money for sienas solid fly and clutch,where do you get the clutches with the sprung hub for the s4 as surely the standard s4 isn't sprung if it's designed for use on a DMF, got two weeks to get sorted as i've got a rr day booked on the 28th

    For some reason the S4 has both a sprung hub AND a DMF, so it works just fine.
