I can't comment on the ST162 but when I had my AE92 SX Corolla throwing some bigger swaybars into it was the best thing I did suspension wise.
It had lowered KYB shocks and king springs along with all new bushes and ball joints, which made an enormous difference, and then when I put the swaybars in it was almost that much improvement again.
I would stongly suggest putting swaybars in. Most things i've read suggest the rear one makes the most difference.
