I'm in the same situation.
Netrix is a rubber replacement for the spring plate bushings It's a Weltmaster Product. Performance products sells them for 51.98 a set.
I ordered some from Pelican Yesterday (I forget the price.)

I'm not sure they make a bananna arm in rubber. Maybe porsche only.
The front A arm rubber bushings come on the A arm only and I haven't seen a rubber replacement.

Go to elephant racing site to look at their polybronze bushings.
Good stuff, but expensive probably over 1K for all. (A arms, Mono balls for the top of the strut, spring plate poly bronze, bananna arm monoballs.)
I noticed Performance sells a bannana arm monoball with or without a seal. Big difference in price It looks like they also have a kit to add the seals to previous sets.

Keep us posted. Can someone confirm what I wrote?
