Sub'd for an interesting build..
while it sounds like you'll be in different circumstances than I was, I had my steering rack go out from popping a fuse on the battery (woops) and had fun driving around for a day without any power steering. It was tough. Parking lot speeds are a given, but even at higher speeds, you still get an arm workout. This is with 305s up front.
Perhaps you could make things work better if you messed with caster. Like some others have mentioned, I would use some sort of power steering.
