Installed a Pioneer Balancer that I got from Summit Racing and it dramatically smoothed out the engine and RPM roughness. The OEM one looked a little out at idle but I really noticed the rough engine under heavier loads. I also had an occasional vibration or rattle when the car was in gear but at very low RPM. The rattle sounded like it was coming from under the passenger floorboard by the transmission or H-pipe and it is now gone after installing the new balancer.
Just a note, if you still have your OEM balancer and have a rough engine the Pioneer Balancer from summit is a high quality piece and works great.
