Are there any decent options to consider for my car? I may have to change the clutch/flywheel soon and wonder if staying stock is best or for no much more cash I can get something better.

standard will be the legendary DMF (dual mass flywheel), personally i'd replace it with a single mass to save any future bother LINK
You can keep the standard clutch setup and buy a single mass flywheel to suit your application from Kalmar union.
Don`t buy a cheap single mass `cos had one on my wifes golf and no gear would engage so had to put a dmf one again as had no time to wait and I was visiting my cuz in Nottingham.Also there different opinions about single mc`s effect on g/box.Choose wisely.
thought the clutch plate on a dmf had no springs. am sure you need a different clutch
What are the benefits of swapping the DMF for a SMF from Kalmar/TTV, apart from improved longevity?
What are the draw backs?

Hrm, I see, and the only benefit is that it will last longer than a DMF? How much longer I guess is the question.

& alot cheaper
Guys, this is all relative. Depends how the car is driven as to whether the DMF fails before the actual clutch. The main purpose of a DMF is to eliminate clutch judder. A clutch can be worn and starting to judder but in a system with a DMF it smooths out the take up of drive and increases the longevity of the clutch wearing surfaces.
IMO if the car is fitted with a DMF then i would always fit the same. Fitting anything else could cause other problems with the drive train.

Thats called 'Advancement in technology'...or....'Moving on'....
The V70R moved on from the 850R technology for a reason!!
Your not meant to go backwards.

i agree with t5lee. the long term affect of the solid flywheel will put more strain on the shafts clutch and gearbox. chances are a dmf will out live two cluches anyway. the ca in question is low milage anyway. dont forget the 2.4 t5 from the later model has more toqure than the older models.
there are many suppliers of dmf for the s60. luk do a dmf for around £300 same quality as oe. who do you think makes dealer parts. for £750 id expect to have a everything thats hidden in the bell housing replaced for that.
Think I will stick with the oe clutch and DMF. Going to get the slave cylinder changed soon and the clutch, hopefully the DMF is fine at 54k miles. A new LUK clutch with slave cylinder is £273 and a new LUK DMF is £367 so pretty much the same price as a SMF. Thanks for the help guys.
One other question, when getting the clutch/slave changed, another of bits in to get changed? I've been told Rear Main Oil Seal is a good idea to change with the box off.

nothing i can think of. some on else might be able to advise better but i cant think of anthing that would need replacing
I recently upgraded my clutch - replaced the DMF with another one - because the DMF is much kinder to your drivetrain & crank shaft. Torsional shock loading of the crank via an SMF can in certain situations snap it.
I put in a SACHS motorsport clutch which is a lot heavier on the foot but you know it will never slip & takes a lot more oomph. Downside is that it is hard work in slow traffic & it is a bit digital.
Depending on your objectives for the car I think it is an excellent setup for fast road use.
Do you understand the mechanical difference between a DMF vs a SMF?

I have never seen a DMF outliving 2 clutches,it may outlive one but in alot of cases not even that.Basically yr running gear get less stress using a DMF where is SMF will outlive 2 clutches no probs.I mean if the g/boxes the same as older models running on SMF how many cases of damaged g/boxes and the rest of it and what power was it running is a quastion.If as mentiond above they run the same g/boxes as older models I can`t see any problem fitting a SMF in wich case u could put an uprated clutch in to last longer but again it is down to the power and how it`s been used.
