00 Camry LE Suspension upgrade, its too soft

Well having the car I've felt that my driving experience has been separated from the road for over a year. This car is nice but not fun to drive more like aggravating but with reliability and economy. Taking turns on the highway and lane changes feel very erratic car dives left and right and also front to back when braking. The steering feel is off, but I can live with that it should get firmer with aftermarket suspension. As I looked for performance suspension parts I couldn't find anything I need some ideas on what’s the best parts out their. It may need springs, swaybars maybe something else, thanks

stiffer springs will give you a stronger more aggressive stance and the sway bar across the top of the engine from strut to strut will stabilize the front so you don't feel that roll when you switch lanes.

Toyota 97-01 Camry 4&6Cyl
Springs-Eibach, Tein S,H Tech or coilovers
Struts/Shocks-KYB gas charged GR2 I think
Camber Kit-might be requried and alignment
Swaybars-Addco
Strut Tower Bars-don't know brands
Lexus ES300 97-01 shares most parts
