Look at the GS, The Fsport has:
-four-piston 14 Inch front brakes compared to two-piston 13.1 inch in the non-Fsport.
-265 rear tyres compared to the non-Fsport.
-It has more aggressive transmission tuning.
-2.3 turns lock to lock steering.
They really tried with the GS, i can't say the same with the F-sport
While the ES, somewhat better sportier suspension, a body kit.
