I have my d2's maxed in the rear and slightly lower in the front and i noticed what many refer to as "bumpsteer" after i dunked the shit out of it. i don't really notice it anymore and i think the fact that you're used to driving slammed s13's is the reason you are unaware of the existence of bumpsteer. I also am now rocking the SPLPARTS bumpsteer-reducing endlinks so i get none whatsoever!!
is your car really that low? i mean, you have aero and it is still on so it can't be that bad. or is it?
