The IMS bearing revisions made the issues WORSE! The early cars have a double row bearing, mid year cars have a single row bearing with 1/2 as much bearing support!!

this was done to allow bearing removal and replacement so Porsche didn't owe you a new engine under warranty when it started to take a crap.

They all equally suck, I received a phone call yesterday from an IMS victim with a failure of a 00 bearing at 37K miles.. Today I have gotten TWO calls, one from an 02 Carrera owner and the other from an 04 Boxster S Owner.

Last week I had 7 IMS bearing failure calls, and two D chunk failure calls...
