I installed the yellow Konis on my 2015 GT. The car was "bouncing" sharply from side to side over our uneven rough Maine roads. It was so bad that I never used the "comfort" setting on the steering because, combined with the "bounce", it would cause an unsafe condition by allowing the steering wheel to be yanked back and forth.

The Konis made a HUGE difference. It does ride a little rougher over the bumpy roads, but the car is much, much more controllable. I have them set at 1 turn from the softest on front, and 1/2 turn from softest in the rear. I can now run the steering on "Comfort" all the time. The car is much more pleasant to drive.

I got the Konis from Tirerack.com. In my opinion, well worth the money.

Just wanted to post in case other people are considering making a shock/strut upgrade.

 

Thinking about shocks and struts. Cool outcome for you.
