Porsche discloses frequency of IMSB failures.

My 2000 'S' had a mint condition double row in it when I took it out at 55k miles. Of course now I have an even sweeter LNE double row installed and never ever think about it.

Side note, my new 981 likes to run around in long gear 7th all the time in the 1400 to 2400rpm unless I'm having fun which is most of the time so far. Sure glad the bearing is gone now!
