I just got these tires about a week ago and the first time I drove my car with these tires, I immediately noticed how quiet and comfy they are (compared to the General Exclaim UHPs I had) I can actually hear wind noise now haha!
Then I took them to the autocross in the rain, and MY GOODNESS are they grippy - granted it was soaking wet - but that's what impressed me even more! I am yet to use them in a dry autocross event, but so far, it's looking promising.
I really can't comment too much on dry grip just yet but I've done some spirited driving on a mountain road, and I immediately felt a superb amount of stability and it definitely feels like i could push the car much much more.
Two thumbs up Michelin, I am thoroughly impressed. Please keep up the good work!
