Boxsters 2005 to 2012 are 987's. 2013 and later are 981's. 1998 to 2004 are 986's.
Lots of opinions on what to do about the IMS. Read Mike Focke's pages for a good overview.
If you feel that you have to do something about the IMS, the only option I'm aware of for your 2008 without an engine teardown is the Direct Oil Feed approach from TuneRS Motorsports.
The GT3 wing is a matter of personal taste. It does differentiate your Boxster from other Boxsters.
Good luck with your new Box. Enjoy it in good health!
BTW, on this site, if there are no photos, it doesn't exist!
