Is there anything that I can do to my set up so the ride is smoother and more cushioned, like change springs or something in the suspension? I don't want to lower it or anyt of that, just make it smooth over bumps and less rigid. Dqmn thing rattles over every pothole. My understanf is most spring and suspension kits are for racing and make the ride even more stiff and hard, I definatly don't want that.

 

If I'm not mistaken, the V6 has softer springs and shocks than the GT does. You might want to take a V6 for test drive and if it rides like you want, buy Ford V6 specific suspension parts (shocks, struts, springs, roll bar) and swap them out.

Aftermarket, you are pretty much up a creek without that prereq paddle! People generally don't buy Mustangs and then try to make them ride like a Luxury car, so folks don't make those type of parts.

 

AIr Ride Suspension. : ) How low can you goooooooo!
