Hey guys, have a 2007 xr5 turbo here in aus (st225 I believe to the rest of the world) however it has a motor from a 2009, which I believe is facelift? Anyways, its stage 3 bluefin tuned and the clutch has started to slip (car has 250,000 klms, 200,000 on the motor) was just wondering what the torque rating of the stock clutch is and if I need to go heavy duty? I'm thinking I will get a single mass conversion done as it ends up being a lot cheaper, and also gives me the option to machine the flywheel if there are any further issues. Am I correct in assuming the single mass is also capable of holding more torque than a DMF? I believe the stage 3 bluefin puts out 227kw (305hp) and 452 nm. Not sure how close I would be to that power level, but would like to know what clutch I will need.

Well after a quick search on the old internet I couldn't find the answer.
I see Dream Science has an upgrade that they say is good for 420 bhp and 430 lbs/ft of torque.
Whenever I have been forced to change a clutch I go with something more heavy duty then stock.
maybe try this forum:

RS clutch will cope with that power level easily, I would stick with the dmf, as a solid flywheel can rattle at idle, my old ST225 had the RS clutch and it felt quite easy on the left leg, as said above, go to focustoc.com for loads of 225 information.

Yeah got a quote of $2600 for a factory replacement from a general local mechanic, emailed an euro specialist guy and hes gonna do a Xtreme single mass and organic sprung clutch for $1900. Considering i could only find that kit for $1500, id say its a well fair price.
