F430 Carbon Seat

Now maybe I am a Fat B*stard but my large 430 Carbon seats do not have as much room in them vs my CS despite both being large. Normally I drive 430 in my suit going to work (which is obviously very fine thread) or my shorts when I am going waterskiing on a weekend. However, when I recently went on a trip to the Ferrari factory in my Levi's I was surprised how tight it all became with that small difference over several hours. So I unwrapped the seat base side foam bolsters and sliced a small section of the foam insets off. what a good move that was, as after reinserting back in the leather, its a dream. Isn't that what the guys do at Le Mans ....
