I'm in the market for all new bearings for my long block 3.4 project so this thread certainly interests me. I see a great disparity in 3.2 main bearing pricing (200.00 vs 670.00 from Porsche dealership) So I'm guessing maybe the Porsche dealership is German made Glyco and the other is the s. african version. Well one would hope.

Thinking about the rod bearings being narrow. Perhaps there's a design change that Porsche did that proved that the rod only needed to ride on that 17mm width vs a wider (more material) bearing. It stands to reason that less material = less resistance right? I haven't seen anyone put forth a mechanical reason for the apparent change which seems to be affecting multiple vendors. Maybe there's a tech bulletin?
