Chip Collingwood at UK Motorsports in Virginia has some of the best quality
urethane bushings I have seen. They come in three different hardnesses.
For the rear trailing arm bushings on my street(5 years) and race cars I use
the Richard Goode nylatron kits. They are very well engineered and if
installed correctly only slightly change the ride quality. For the better in
my opinion.

Might be worth noting, in case anyone else wants to try this, that the
castable
polyurethane comes in many different hardnesses as well. As I recall, there
were formulas from 40 shore (which is about the same as the EPDM 'rubber'
bushings) to over 90 shore, which is very hard, almost like wood.
