I just got some AX6 pads and have bedding them in three separate times. The squeal is still to unbearable for the track let alone the street. The odd thing that I and Carbotech cannot figure out is why they are louder hot versus cold. Most aggressive pads will squeak a bit when cold, but mine are silent until warm/hot.

I wouldn't at all recommend them if you're looking for quiet. They're very noisy. Switch to the Bobcat's if you want to quiet them down.

I had to bed them in 4 times before they started to get quiet. It lasted two days and I have some noise back. I planned on downgrading to the Cats but CT convinced me to stay and try to bed in more. I will see what an auto-x does this weekend and decide.
