What are you guys running for tire pressures? I've got the stock 415mm wheels and the Ferrari factory sticker on the windshield lists the tire pressure at 3.0KG/cm2 (which converts to 42.6psi !) front/back. The Amerispec sticker in the glove box lists it at: 38psi front/back at maximum load. The stock Michelin TRX tires are stamped 36psi MAX on the sidewalls... ????????
