    Hi,
    Due to a part being missed from my Sachs Clutch kit, I've been offered a Helix kit instead.
    Anyone on here running Helix on their stage2+ S3 or Ed30 ?

    No idea which bits are missing, clutch had been on order since before Xmas, I guess rtech were probably concerned it wouldn't arrive before friday which is when I'm travelling up for fitment. Will drop mrgicm a PM for his thoughts.

    I have a Helix clutch + SMF and its just perfect, holds down much more agressive when changing gears , it pulls instantly and the flywheel is 6.4kg lighter than OEM. I am very satisfied. The clutch pedal was a litter harder the first thousand kilometers but now im running Castrol SRF racing oil in the clutch, alonfg with stell lines and its just perfect, for everyday driving and for track use.... This clutch can hold up to 580nM....

    The Sachs equivalent is rated at slightly less(530Nm or 390lbs),and the DMF Sachs is said to be good for up to 360lbs+ or the thick end of 500Nm.....certainly I've had no problems so far putting 360 lbs through mine....cue clutch burning up!

    Is the flywheel lighter or does the weight reduction also include changing the DMF ?

    Sachs DMF???

    All Audi S3 8P's are all fitted with LUK DMF's

    I know this because i have a sachs performance clutch fitted with brand new LUK DMF , i asked audi to supply me with a Sachs DMF for the s3 8p at the time as i had read on forums Sachs had a stronger DMF available. They told me they do not list one fo any S3 8P 2006 - 2010, i have etka and i confirmed this also. I then phoned Sachs and they do not manufacture a Sachs DMF!

    If you are fiting a new DMF with a performance clutch the only one available for the S3 8P is LUK

    thanks Davie,
    I'm not planning on replacing the DMF unless essential.

    Sorry davie...you are of course entirely correct,and what I should have written was the Sachs performance clutch for use with the LUK DMF.

    I can only say i was rather busy at the time this afternoon and should have checked what I had said fully before comitting it to the internet.

    My apologies....

    Dont worry about it, i was just clearing it up as i spent hours searching for the mysterious Sachs DMF and finally found out it was non existant lol. There is confusion on forums that 08 or newer S3's are fitted with Sachs DMF and Clutch which is INCORRECT.
    They are fitted with a full LUK setup (DMF, Disc, Plate) If you read Elsawin it tells you NOT to fit the LUK parts with Sachs parts. As there is only LUK DMF's the conclusion is all new S3's are fitted with LUK DMF and Clutch. The only time the OEM Sachs clutch might be fitted is if the car is booked in for clutch issues and Audi decide to deviate from Elsawin and fit the OEM Sachs Clutch.

    Hope this clears everything up.

    Cheers Davie

    this is a job I fear is looming for me in the next 3-4k miles.

    I wanted to fit a SMF to eradicate the issues associated with the DMF not being able to cope so well with the higher revs, but I've been advised strongly to stick with the DMF as an independent garage I use has seen a few longer term issues with SMF's and cracking cranks. I want to do a fair bit more research before I bite the bullet either way, but I need a better clutch than the one that is in there (OEM), but I don't want any change in the pedal characteristics as the wife drives the car a fair bit and hates heavy pedals. Too many choices:sadlike:

    Warren,
    I have exactly the same brief as you.
    I'm led to believe that the Helix and Sachs items once bedded in are very similar to standard.

    Mines being fitted tomorrow (hooray) so I'll report my findings.

    Nice one, really appreciate it. I can feel my car is just at that point where at maximum torque there is a split second before drive is commenced. Cold weather doesn't help, but in a few thousand it will be slipping again (last one lasted 11k, this one has lasted for 24k which considering spec is pretty good).

    Very interested to hear your thoughts robern2, as I don't think another OEM unit is the way to go.

    After 2 and a half months of nursing my slipping clutch it was finally replaced yesterday in favour of a Helix item by the helpful chaps at Rtech power.
    The DMF was in good working order so did not need replacing.

    Whilst the clutch is slightly stiffer than standard, it is by no difficult to use, testament to this being the hour of clutch/de-clutching on the M42 thanks to the kind people slowing down to gawp at a car accident. If anything it appears to have softened in the 150 miles I’ve covered since.

    There are no strange squeaks or rattles in operation, gear changes are now very precise with much quicker pick up than before.

    That's good to hear.

    I am going to have to use the money I'd saved up for an exhaust / DP / cat for a clutch & DMF (assume both, and hope for the best I need the clutch). Needless to say I'm annoyed about it, but its part of the course I guess. Thanks for posting back, glad to hear it's doing the trick. Bed it in carefully as I've heard rumours you can run a clutch if you give it too much stick bedding it in.

    I raised the question of bedding in with Rtech, they suggested there is no real need.

    it's best to speak to rtech - my Sachs clutch had been on back ordersince december and something was missing from the kit. Rtech were kind enough to offer me the Helix kit at the same price so £780 inc release bearing was pefect.
    I'm sure the Sachs is a great unit but the fact the Helix can handle that little bit more power yet still retain perfect road manners is the perfect combination for me.

    It's stil DMF, the original infact as mine was fine.
    I may have misunderstood but didn't someone post on this thread earlier about the bhp/torque limits being higher with Helix that Sachs.
    Either way, I'm sure both are quality bits of kit suited to our applications.
