Now that I've driven the car a bit, I'm pretty sure I hear more noise. It's not loud, but I think I hear something that wasn't there before. It reminds me of the sound that a dragging brake pad might make, but I'm confident that there's not an issue with the brakes. I suspect that the bushings allow more minor vibrations to be transmitted into the frame/body where they resonate a bit. Granted, I'm not sure what sort of noise would be contributed to by harder rear sub-frame bushings so this is mostly a big guess on my part. LOL
I haven't noticed any extra vibration.
I also had the front sway bar re-installed at the same time the rear SF bushings were replaced, so overall the handling went from "This feels like a 70's land barge" to "YES! This feels like a BMW!" I'm not sure how much of that is due to stiffer rear SF bushings though.
I went with the purple PowerFlex because my mechanic suggested that a stiffer rear would better complement the front X-brace and Mason front strut bar. Overall... I like it. :-)
