[alfa] polyurethane for Spider

Young Mr. Robrock asked about poly bushings;

Karl,

I can't really find a negative to poly for Alfas. I like the PowerFlex line 
and sell it because I perceive it to be a premium product. It has stainless 
steel inserts, the design has always been split, and poly is, in my 
opinion, a great material for suspensions. Durometer ratings vary depending 
on application as well. Oil resistant, no joke, it's a big deal in Alfas. 
Rear trailing arm bushes go bad and  make the car "crab" under power. Not 
pleasant.

The trailing arm kit is nice as the side washers are built into the 
bushing. Simple 2 piece design. i am planning to do some articles for the 
mags on install, but it's the barbecue for me. High intense heat all around 
the bushing for a shorter period and the rubber pops out. Much faster and 
less clean up. Trailing arms are just alot of grunt work. I'll be happy to 
assist on these installs for the PowerFlex, it's not really too bad. 
Results make the scuffed knuckles fade quickly. :) Soft poly bushings 
should not lessen the driving experience, but improve it. Not harsh either.
