The fluid bearing in stock S65's is inadequate indeed compared to an M20, but factually the most wear per revolution does still occur during startup. Carry on.
I have an 08 with 64000 miles and will likely get the bearings done around 75-100k, most likely at your shop. Im the farthest thing from a mechanic but a lot of times I see reference to start/stop cycles when talking about bearing wear which is consistent with your statement. That said, do the OEM bearings remain inferior once the car is at operating temperature? A lot of us are red light Mario Andrettis, I can't imagine that type of driving and associated loads can be good for any rod bearing...am I correct?
