I'm very happy with comfort, I didn't expect soo much form tires of this kind. Driving feeling is special, much different from regular tires, I don't know how to describe but it's really nice how predict the handling can be if the car is tuned properly, If you suspension can't handle so much grip as these tires offer, then these tires can't do their job at their best..
Dry grip is just breathtaking!
Tires are still so sticky even if they're old, they pick-up every last piece on the ground, it's kinda frustrating if you run car without inner fender guards.
As for the bad thing, I don't recommend them for wet surfaces at all. Tire wear is very high, they have have very limited life, but hey this is perfectly normal, if the tire have superb grip on dry surfaces they fade away fast! I still rather run tires that are used to be driving hard and gives u the best performance than tires with "400 tread wear" and you unmount them before they even worn-out because they're getting old and rubber became hard that means bad tire.
