One of the biggest drawbacks about Nylon is that it's hygroscopic.  With the presence of moisture, the strength of Nylon deteriorates.  Running these things UNDER the car is just asking for trouble.  (Do we all drive in the desert?)
Delrin, on the other hand, is unaffected my moisture.  Hardness and physical characteristics are virtually the same with Nylon.  Delrin is a bit more resistant to chemicals and petroleums; Nylon tends to swell when doused with chemicals or petroleum based fluids.  Both deteriorate under attack from acid.
I'd like to see long-term experiences from those running these Nylon bushings, especially from owners who live in humid area or areas with constant moisture, like rain...

Nylon 6/6 (glass fiber reinforced) is hygroscopic, but will only absorb 1-2% water by weight, and will lose the moisture eventually as it "dries". The bulk of the bushing is protected from any contact with water or chemicals inside the suspension component, with only the alignment flange exposed to outside environment anyway.
In addition, no one that I know of is having trouble driving through pools of acid, and Nylon 6/6 is highly chemical resistant, especially with petroleum based fluids. If anyone doubts, I'll be more than happy to measure a bushing, drop it in a can of oil and leave it for a week and then measure the difference in dimensions.

Are you sure about the delrin? A lot of us have delrin bolts in our paintball guns (the bolt in the sense of the thing that closes the breech, not bolts that hold it together) Anyway, word on the delrin bolts is to keep water the hell off of them or bad things will result... it could just be a rumor though.

Hey Jimlab,
I'd be happy to provide you the pieces for modeling after the autocross season. I'm just up north of you so I could get them to you easily. I'm planning to take it all apart then anyway.

I recently installed just the Energy Suspension Front & Rear End Links. I'm stunned at what $12.83 in "plastic" did for the handling. (Ultrarev.com sells the partial and full kits.)
Will probably do the sway bar frame bushings next, not sure how challenging they are to install...
FWIW, the Energy Suspension bushings are polyurethane. This is helpful, (not)...
