Are you on the original struts and front mounts? If yes and more than 60K, I garontee the mounts are toast and mebbe the struts too. These will both make a huge difference in the bump response.

After that, consider going to a 15" wheel and higher profile tire, H rated or lower. The lower the speed rating, the softer the sidewall. The taller tire on the 15" wheel will also filter more road shock. Save the 16" wheels and when your back is better, you have summer and winter wheel.

But only after the shock mounts and shocks. Real beeg difference there.
