Bruce---I have a slightly different take on the use of suspension
bushing material. My thoughts are that, so far as ride compliance is
concerned, these bushings are far down the list on what makes for "stiff
riding".
Most of the ride compliance is found in the tire. If the sidewall won't
"give", either thru its shortness, stiffness, or inflation pressure,
uneven road surfaces must be taken up somewhere else.
Now we are at the springs and shocks. If these are firmer than stock,
along with the above mentioned tires, then the body has to soak up the
shock surplus, and this is what will be felt.
Bushings are just pivot points for the suspension to move around. Denser
material should not of itself make for a ride that's too stiff.
Denseness will, however, help make the wheels follow an intended line,
reducing squirm, so this is good.
I found no ride harshness change when going to the urethane, front and
rear suspension bushings.
It would seem reasonable that the more dense the bushing, the longer it
will last. Mine have been in for at least ten years, and about 100,000
miles. No squeaks after the initial application of my own moly-lube.

I need to redbush my front end and would like some input from the group.
TRF has 3 different kits: stock rubber, performance urethane, and race
quality nylatron with prices almost doubling from rubber to race quality
(although price is not necessarily the driving factor here). I'm leaning
towards non rubber and would like to know if there is a substantial
benefit to the nylatron vs urethane and is there really a harsher ride
with non rubber. Would appreciate recommendations.
Thanks,
