Question??? Improving handling on a sedan

[CASTREX]

For you all Yaris Doctors:

My current set up includes Tanabe DF's210 and Strut bar, 15" Koning Helium wheels, 205/50/15 Kuhmo ecsta tires.

What will be the next bolt on that would gain more improvements?

How does it drive? When you're barreling into a turn, what do you wish would happen? If we don't know the answer to that question, all suggestions are simply someone naming an aftermarket part.
