I just upgraded to the on3 performance single turbo. After replacing my stock struts with coilovers I think I need to replace my bushings. the ride seems harsh and even violent at times. I dread any travel that involves anything but a new smooth roadway because of the rough riding front and rear end. SO can someone tell me the difference between Hydro and non-hydro bushings, as well as, the benefits and disadvantages? I'm new to the replacement and or upgrades available today with suspension options so any help would be greatly appreciated.
