4kcsq Subframe Bushings

[Mason Bender <mbender@freenet.columbus.oh.us>]

Dear Quattrophiles-

It is time for me to replace subframe bushings on my 86 4kcsq.

I know that some of you have recently replaced them with Eric's delrin
bushings, and I was wondering what the difference is between bushing
types.  The people at Hoehn told me that out of all of the 8 bushings
(front & rear), there are 3 different types.  I was under the impression
that they are all the same.  What is the difference between?

How have Eric's delrin bushings effected ride quality?

TIA,
Mason B
