I have a 2004 G35 coupe, and like most sportscars, its not exactly the smoothest ride in the world due to the tight suspension (I'm assuming that's the cause of it). Does anyone have any suggestions on how to improve the smoothness of the ride, so I don't feel (hard) every single little bump in the road? Does anyone know of a special type of suspension upgrade, shocks or struts that would help? Thanks in advance for your input.

 

Check your tire pressure. Too much = a stiffer tire. That can contribute to the roughness.
