suspension help

i have a 99 civic si lowered with eibach coilovers and tokiko shocks when i get to about 80 the car feels like it is real loose it likes to move from side to side could someone tell me what the problem could be? do i need sway bars, camber kit or what.

you probably need an alignment

Check all suspension parts for worn/cracked bushings, bad ball joints, etc. Your alignment may be off. Check tire pressure. Upper/lower tie bars will stiffen up the car some what. Sways bars wont really have an effect on this issue but is the next best upgrade besides tires, shocks, springs. More attention is needed to the rear sway than front on FWD car. When autocrossing i use no front sway. Stock sway for street usage, the ST front bar made the understeer worse than FWD cars already do.
