Nylatron- harder than stock, but softer than Polyurethane. Can be brittle
especially with age.
Polyurethane- harder than Nylatron, but will last nearly for ever.
They can squeek, which will bother some people. Some say they
are more resistant to oil/gas/grease than the above too.
I'm putting polyurethane bushings, a-arm and trunion, in my '78 Midget.
I got them from Faspec.
I'm using them because I'm looking for longevity, rather than
handling, my only concern is the transfer of road shocks to the frame
may cause some additional stress on the mounts and etc.
I'll post how the ride is when the car is back on the road (don't hold
your breath).
