The elephant in the room on these cars is the IMS bearing, but both the 2006 late M96 and M97 have the same (updated) IMS bearing.

Typical porsche marketing, splitting hairs for their consumer base who split hairs. I see the same with the current gen. I've driven more than once, the 2013+ boxster, cayman, S or GTS, did not see a difference. In fact, with the slight weight add, the 911 base 3.4 felt the same as well. That's a hp range from 315 to 350. My 315 feels very strong - to me.
Do all 2006 987S 3.2's have the same IMS bearing as the 3.4? Is it strictly the 2005's with the weaker (?) older version?
