I'm at 45k and about to do an oil change again (I change it every 3k miles). Last time I did it, I noticed a few (about 5 or so small metal pieces in the filter so this time I will double check. Hope it doesn't get worse!) I hope we are blessed with a car like yours. That's an amazing achievement. German engineering ftw. Don't worry too much about the metal flakes. I have spoken to a very reputable 996 turbo engine builder that said he has never seen an oil filter without at least few small metal flakes. My guess is that whoever says they have a totally clean filter every time is just not looking hard enough, the flakes can be really small and hard to see.

We mic'd the clutch at that point and found it be 90% material left compared to a new factory - I think mine mic'd at 1.6mm and the factory new was 1.7mm - in either case it was within 0.1mm difference. We replaced the RMS, two bearings and put it back together - to me I wanted to see what a factory clutch could do over time. There were no stress cracks on the pressure plate or at the spring retainers in the clutch at that time.

FYI - dragging is not my gig - love hard launches but drag racing is just not for me - now a track with some uphills, downhills and some twisties...well that's another story. Also that clutch has seen bumper to bumper traffic 2+ hours a day for 3.5-4 years of it's life which can be equally hard on a clutch.
Maybe I am just lucky....maybe I'll just keep knocking on wood..

When I saw the 250k on the original clutch, and 90% material left after ~172k miles, I assumed it was mostly highway miles. I was surprised to see your post that it did 3.5-4 years as a traffic commuter. I don't care how good you are with a clutch in terms of starting without revving that's just a crazy amount of mileage! Your clutch must be from a batch with a lot harder material than normal!

Congrats on making it to the 350k. I'm only at 55k miles and would love to be at much higher mileage but I work from home so the car very rarely does any commutes and only gets maybe 5k miles a year. The first year I owned it when I was still commuting I put on over 20k miles in 9 months but since then it's had a couple of years with only maybe 3-4k miles on it which makes me cry thinking about how much it sits!

I can't wait to see when you hit the 500k mark!
