I'm not sure if it's the word you're looking for but tramlining is where the wheels will follow imperfections in the road instead of where you want the car to go. Increasing scrub radius will increase tramlining if everything else is kept equal. Some tires will tramline more than others too.

Yeah, @revaholic mentioned feeling the steering wheel pull when crossing railroad tracks. Seems about the same.

Thanks for your input guys...I didn't think about the FWD vs. RWD difference but that could explain it. Also it seems like there is a balance that needs to be struck between kickback and high speed stability, and in terms of this I think the tuning of the FRS towards stability is definitely advantageous.

Never heard of that word before but I know exactly what it feels like, particularly in that old Civic of mine. Learn something new everyday!
