Feeling over streering while turning hard

[yariseggvvti]

I haven't lower my Yaris yet but I had install UR 23mm rear sway,rear UR brace bar,Nitto trailing arm bar and add one more bar in the Nitto trailing arm bar. I will say four bars all together and one more UR rear strut bar. In the front with UR upper strut bar, UR lower 4 point brace bar.I had feel every little bump with out lower. The whole chassis feel stiff. I am running stock 15 with 195/60 all season tire. Now with out lowering it and handles good. Final step is going to put the Tein basis on. Any good advice? Thanks!
