based on the 6 weeks of ownership so far
I noticed an immediate change in comfort. Ride is less hard when going over bumps compared to the original Michelin AS pilot tires. I still feel the road but less hard. I feel the noise seems to be less though I'm not measuring with any device. As for handling I have no comment because I don't drive aggressively to notice. I drove one time in a down pour and it handled quite well.
