Help wanted: Need torque specs for clutch replacement job

[electricbrew]

Hey guys (and ladies) -

I was trying to get ISTA/D installed before I tackled my clutch job, but I could not manage to free up enough space on my tiny ass laptop drive and my car's already been down for weeks so I got impatient. Anyway, can someone w/ ISTA access please tell me what the torque spec is for the pressure plate to flywheel bolts please? I've googled a decent amount and can't seem to find info for the F8x specifically.

I'm not replacing my flywheel (luckily), but just so that it's a good reference for others later on please also include the flywheel to engine bolt torque spec and if it's not too much trouble, the bell housing to engine bolt and driveshaft to guibo torque specs as well. TIA!

Thanks for posting this information. A couple of questions for the clutch to flywheel and flywheel torque specs. Other sources quote the flywheel bolt torque as 120nm. Is that for steel bolts, or is 60nm + 45 degrees = 120nm? Similar question for the clutch to flywheel.

I conducted a test using wheel mounting lug nuts on my car, as the torque specs are similar. I first tightened to 60nm and then turned the nut another 45 degrees. Then I adjusted the torque wrench to 120nm and found that the nuts were already in excess of 120nm when applied.

In application to installing the clutch and flywheel I found that while achieving the 60NM + 45 degrees was mostly achievable. However, 15NM + 90 degrees was not possible with a normal ~18 inch handle, so I got as much of the angle as possible, but it felt like going further would break something based on my previous experiment. The flywheel threads were new with the factory blue thread lock applied. The clutch and flywheel were low mileage takeoffs from another car, so perhaps that accounted for some level of pre-seat that impacted the total angle required. Anyone with experience installing new vs used that can speak to this case?
