Use 90.5 as they are "thicker" and will stay round much longer. Only use the Doghouse cooler. A trick way to go is to use the 911 cooling shroud system with the extra cooling you could go to 94mm. It would look like a 911 when you pop the deck lid.(Only your hair dresser will know for sure.)Where are you located? Steve 818 508 0582
