I used to own a 2013 GS350 non-Fsport and now I own a 2018 gs Fsport. There is a huge difference in the suspension tightness and lane floating. The 2013 handling and steering tightness was much better than the 2018.

What did Toyota change and any recommendations on how to improve?

 

Had a 2015 F-Sport lease and bought a new 2016 F-Sport after my lease ended. Noticed it right away as soon as I got on the 405 freeway on my home, love the handling and sportiness of the 2013-2015 F-Sport in Sport+ mode.
