Yes the clutch disc was much worse than I would have expected, it's the original clutch from new. The SMG robot probably would be cursing while moving from standstill, it did an admirable job to be honest. Now the car kinda drives like a normal auto box if you don't step on it. It is one fallacy of the internet it's bad in slow speeds, it actually drives well in low speed. What it doesn't do well is somewhere in the middle, where you don't step on it or being gentle on the throttle.
What was a really bad was the release bearing guide, sorry forgot to take a picture of it. I guess the amount of power that goes into the clutch system during high rev, upshift and downshift is really puts a lot of pressure on this part. If you have a M5 or M6, make sure to buy the newer part 23117564680 which has superseded 23117539951. Jon thinks that the release bearing guide may also contribute to the rod bearing wear due to undue stress to the crankshaft, aside from the fact the tolerance of the bearings are really tight. Jon double checked all of the rod bearings, torque, etc. Effectively making the bottom part of the engine to be hand assembled, there are theories out there that the mass production of the S85 and small tolerance levels of the rod bearings maybe the culprit. Why also some cars have their rod bearings wear faster compared to others.
I haven't been able to do any high revs, I am still waiting for me to get above 600 km before I try to rev it pass 4,000 rpm. At the current rate I am going, that maybe sometime in 2021. Also all parts are from FCP Euro, so maybe sometime 2040 if they are still in business and I still have the car I get a new clutch for free. 🤣
Jon and I also noticed that this maybe the first time the car had a major service, all of the factory clamps, etc where all untouched. I guess that looks to be correct, as we got the less than 54k kms. Looking the service history in japan there was no service period where it had more than 3 hours of work, so assume only prescribed maintenance was done to it on its expected intervals: 3k, 6k, 10k, 14k, 32k, 40k, 52k.
