Yeah I'm thinking subframe bushing to. Seems to happen to s14's more than s13's get the subframe disc thingys drift washer whatever.

list of suspension mods?

are the arms tight/alignment done?
if you have coilovers, are the top hates tightened all the way.
and like state above have you checked your subframe bushings

Not the subframe, just a wheel alignment.
