Will installing a sway bar on my classic car improve handling without reducing ride quality?

Question:

Will installing a rear sway bar on my 1975 Cadillac Eldorado improve handling without reducing ride quality?

Installing a rear sway bar on *your car will improve handling somewhat but do not expect miracles. The sway bar will increase the car’s roll-stiffness, so the sprung mass will be more resistant to rolling. Therefore, the car will not list to the outside quite as much when turning. Handling, however, is a function of many factors in addition to roll stiffness, so altering one factor among many is not likely to have a profound effect.

Answer:

It is difficult to answer the second part of the question without knowing what “ride quality” means to you. If it means feeling like you are going down the highway in that big comfy couch in your living room, then the addition of a rear sway bar will reduce ride quality somewhat. But again, the sway bar is just one component among many that influence ride characteristics.
