I have my car aligned to almost the middle of factory spec for every aspect of the suspension. Yet, at crusing speed (goes away when going really fast) has the tendancy to track (sway back and forth). The parts should not be in question (mod list below), and I have my tire pressure at 38 psi all the way around. I'm also getting severe vibration at around 85-95 mph too, which I think is because my brembo rotors are warped (my tires are zero balanced). My front anti-sway (staiblizer) bar end links' bushings are all popped (no more grease in them). Do you think this could be causing it? or is this another side efffect of my warped brembo rotors? Or perhaps the well bearings are bad (wheels don't wiggle at all when on a lift, and no loud wooshing/metal on metal sounds when driving)?
