        2 2017 GT - ShouldhavegottheGT Installation Time: Less than 1 Hour

        Went out after 2 years.

        Install was pretty straightforward. Rode good for a little bit. Completely blown after 2 years. I don’t track or race my car. It’s not even a daily driver. Just weekends and stuff. Went back to the PP shocks and rides much better.

        Ecoboost Shock Upgrade

        After previously adding Koni adjustables front and rear on a 2013 GT, I decided to try the "street-track" version on the rear of my 2015 Ecoboost. I had previously found the rear "adjustables" a little too harsh for daily driving even at the softest setting on the GT, but the street-track version is almost perfect for the Ecoboost with its Performance Pak option. While the Ecoboost handling is much improved over the non-IRS Mustangs, the rear shock addition added another level of handling when paired with the other Performance Pak upgrades.

        KONI STR.T Rear Shock

        Works very well with lowering springs. I have the Mustang GT with the performance package and when I lowered the car I reused the stock shocks and the ride quality lowered too. I purchased these shocks and the ride quality in my opinion is better than it was with the stock shocks and stock ride height.

        missing link

        The stock shocks did this car no justice. These shocks were the missing link to the performance ride I was looking for. Love the ride!

        Firm up your rear end, no pun intended

        The Koni's are a great replacement shock and really firm up the rear end of my 15 GT, more stable around corners and really put the rubber to the road when needed, definitely recommend.
