RE: Polyurethane bushings

At one time, Delrin was in favor.  Just like Keith is saying, you buy it in 
bar stock and machine it on a lathe.  I did this on my Elan 15 years ago 
and they work great.  The ride is obviously a little harsher, but for a 
racing car, I wouldn't think that this would be a problem.  They were very 
easy to machine and infinitely cheaper than the original equipment 
bushings.  Though I am not a chemist, I am guessing it is just a brand name 
for some type of urethane.

Best of luck,
