I think they made a noticeable Improvement in the handling. They are somewhat harsher, but I have to admit, my front end was so worn, that I could have used bubble gum for bushings and saw an improvement LOL!
That's about where I am, OWB. My AZ Dart "base" model is riding on what may well be the original stock suspension and steering gear. The 6" or so of slack in the steering wheel isn't so bad in grocery getting duty, but that and the 9" brakes make it a pretty scarey ride over 40-45 MPH!
I'm currently about to drop the hammer on a supplier for my suspension and disk brakes parts. I expect to hardly recognize the car when I get to drive it with the new stuff.
