Need some advice from expert..

Hai guys,

I have problem with my EK 2 door handling, a month ago im changing the power steering (becoz the ori is leaking) together with lower arm one whole set, becoz according to my mechanic, it hard if only to change the power steering road only, so i bought 1 set of EK9 steering rack + lower arm together (damm heavy!!).Im also changing the suspension from adjustable tein to standard EK9.

So after installaton everything seem ok, but a few days later i notice, at >120km/hrs, my car start pulling right n left, like lost of balance at high speed,it not much, but u can feel it,expecially when u start "tarik" at trafik light. i already do the aligment and balancing, for ur info, im using standard B20 engine.so i wonder::hmmmm:

1) Is it EK9 standard suspension can't handle B20 engine? is it too soft for my car?
2) Or is it because of the whole set lower arm that i change?
3)Or do i need to re-aligment and rebalancing again?

hope u guys can help me with something..

thanks..
