We have a 04' sport model and my wife said the other day that it rides rough/firm. I told her it was because it was the sport model. I decided to look into struts and found Bilstein has 2 options for the car. The B4 standard, sport, and HD struts for the front and the sport and HD shocks for the rear. Can the standard suspension struts even be used on a sport model? They don't make a standard suspension shock for the rear though. Would any of these options give a smoother ride than the factory labeled"sport" struts and shocks give?

 

wytype, they do make the standard suspension rear shocks. Check out eshocks.com for a package containing all 4 shocks/struts in the comfort setup.

As for putting comfort shocks on your car, you should be fine. The sport shocks are slightly shorter, but for the most part, are identical except for the valving in the shock. Going to the heavy duty is only going to result in a stiffer ride as the heavy duty shocks are set up with heavier duty valving to handle being under more weight load.
