So I am considering doing the 9L or 9L extreme upgrade to my 2016 ACR-E. Has anyone who tracks an ACR done this upgrade? I’m specifically wondering what it does to the balance of the car. I find the car to be very easy to drive and very well balanced...I don’t want to kill this by adding power. Also wondering if this hurts the functionality of the traction control at all (all the modes). How about tire wear (which is already horrid with the Kuhmos)?

Also, what do folks think this would do to the long term value of the car?
