How to improve handling of my 2015 Tacoma Double Cab

I bought a 2015 Tacoma SR5 Double Cab 4 wheel drive. I did not get the TRD package because I don't go off road and I wanted a better ride quality. So my truck does not have Bilstein shocks. I would like to improve the handling of the truck without making it ride rough. The truck sort of floats in the front. The truck dips quite a bit going through a curve with the inside going down and the outside going up. Additionally, the front end sort of nose dives when braking hard. I am considering changing out the front shocks/stuts for something more sporty that will keep the front end more level in the curves without losing the ride quality. I know that I can't turn it into a sports car, but hopefully I can make it more roadworthy. Any thoughts about how to accomplish this? Bilstein 4600? Bilstein 5100? or something else.

 

A rear sway bar and shocks will make a significant difference in handling and ride quality.

 

The Baja kit makes the truck feel sporty on the street. Minimal nose dive when braking, minimal body role. It almost makes you want to push it in the corners. Night and day handling improvement over stock.
