Good and also properly adjusted shocks make a big difference in the handling of your model A Ford. My 1930 Model A Ford wandered, bounced and bounced, and was a handful to drive. After installing four new shocks, arms and links, it is hard to believe that it is the same pick up. I am running bias plied 19" rimmed Firestone tires and they are now very livable to drive with. Next time around, I will also go with the radial tires.
