My car handles really well and is as tight as it gets, however I do miss that smoothness that an original turbo Buick gives because I get a lot of vibration and road noise. I have Energy Suspension poly body mounts, HR motor mounts, poly rear control arm bushings, 1LE lower front control arm bushings, and solid upper control arm bushings on my UB Machine arms. Add stiff springs and shocks, and you get the picture. I'm thinking that I need to back off on something and the body mounts make the most sense to me right now. The Energy suspension are 70 durometer and the rubbers are supposed to be 40-45. Do you all thing this would make a good enough difference on noise / vibration? Doing a passenger side rubber motor mount helped, but I want a little more.
