19" will give a harder ride and may not give you better handling as the(rolling diameter rim + tyre) may cause the car to ride higher and thus shift the centre of gravity.
The F20 suspension is designed for 17" (rolling diameter rim + tyre) in the sport and urban and 18" (rolling diameter rim + tyre) in the M Sport.
You may have to have the full suspension modifyied to gain any advantage apart from the look.
