Hello, We have Ferrari portofino and i have few questions. We are on 3000km trip in europe, our ferrari is on original 20' wheels and Michelin Pilot Sport 4s tires. The car is very hard, uncomfortable. I want to drain the tire pressure by 0.4 bar, i done it and car is much better on long trip but the tire pressure sensor all the time shows the error and makes a sound. Is it possible to turn it off or do something to just not bother you? What do you think about Michelin PS4s? I heard that pirelli is much softer tire, so ich much more comfortable. I need to buy windshield to Ferrari portofino, the part number is 7677304, does any of you have for sale? Dealers told me that is not available in factory. Thank you for help!
