When I installed the polygraphite bushings (pretty much in all suspension components) the instructions said "do not lube." Well, the car squeeked like heck..., for a while, and I thought that was a BIG mistake. But after a break-in of about 500-1,000 miles all of the squeeks went away.

The poly bushings give a much better road feel and the car seems to handle much tighter. But then the rubber was quite warn when I replaced it.
