New tires will help quite a bit. But I don't think you have many budget-ranged options. Basically, you can get new springs or a cup kit which is fairly cheap, but manufacturers don't make them softer... They make them stiffer for better handling. Your only option would probably be an adjustable coilover kit with multi-rate springs. You could adjust it fully soft, but I still think this might be as stiff or stiffer than stock. I don't know
Where do you live?
