thanks for all the input. I've got everything out now, so I'd like to do it all now and leave it for the future. I like tec280zx's upgrade. I have one question though. when you modify the urethane part, do you set it up so that the sub frame rests on the urethane on the top and bottom at the same time the lower attachment nut is tightened into the frame of the car? The stock set up has a gap left at the top and bottom when the lower attachment nut is tight leaving the rubber to dampen out the motion / noise when it rotates to the extreme. If that is the case, then I'm all good to go.
Again, thanks for all the input you guys are great!
