I daily drive my '73 Dart with 17" wheels, 1" bars, Hellwig front swaybar, 2 added leafs in the springpacks and adjustable shocks all around.

IMO, A-body Mopars should've gotten 1" bars from the factory.
Watching other cars on the road handle speedbumps and corners I say my Dart has pretty much the same handling characteristics as a modern day sedan.
