Generally the slave cylinder should come with clutch kit. But not always.

No not fitted. But depends who fits it shouldn't really cost Ł200 for fitting

So Ł700 for a DMF fitted was spot on.
When mine went i was quoted between Ł800-Ł1200 to have the work done so i spent Ł800 on an solid lightweight fly uprated pressure plate, stage 3 clutch and OEM slave cylinder then fitted it myself. No need to worry about the DMF anymore and the car will now hit 60 in under 7 second

When mine went it started making an intermittent chattering sound as idle, the noise would go away completely when the clutch was depressed, easily mistaken for a duff slave cylinder bearing. When i removed the DMF it was well gone, you could easily press on the edge of the front face and it would make contact with the rear plate, this is what makes the noise, the two plates touching eachother. I sourced my fly and clutch etc from CFM in america but since then i am told the TTV now produce a solid fly wheel for the ST170 that accepts the larger clutch friction plate, make sure you get the fly wheel for the 240mm clutch plate and not the smaller one otherwise it will slip. Early ST170's had smaller clutches 220mm and they began to slip so the later models got a larger clutch plate.
If you go for a solid lighter fly like mine be prepared for clutch chatter, the lightweight fly allows the gears in the gearbox to rock and chatter against eachother at idle, the noise goes away when in gear and with the clutch down but it is quite loud, it sounds like your gearbox is well broken. I will be honest it gets on my tits quite a bit but it transformed the car

Yeh true that lol.

I was being ignorant as my mates brother normally does my work who charges cheaper than most rip off garages.

If you do change the DMF, where possible you change the crank seal as i believe they are a push (light tap with hammer) fit and only a Ł5 or so, it might save you having to take everything apart again if the seal was to start weeping.
