In debated on purchasing this for a while. Read reviews, watched videos, so figured I would try this.Installation was easy and straightforward, adhesion is good time will tell if it stays that way. Simple, clean with alcohol, then use supplied wipes and done. I did use a heat gun to apply some heat beforehand.I used a decibel meter before install. 70mph highest it got was 83 decibels. After install same road, same speed 69 decibels. So a noticeable difference.I have a 22 performance model 3 with Michelin all season tiresMy recommendation is to make sure everything is clean and well prepared before you stick. Also dry fit the pieces to see where they go before you peel off the back.
