Ive had the delrin's in since almost when the group buy of them came out. (i.e.: I was one of the first to get a set and install them)
After over a year they finally started creaking and squeeking. I put zerk's fittings into them, and shot some lube into the lube grooves. Not another sound from them since. Poly bushings would have needed the same thing.
They aren't "self lubricating" (at least enough to not need additional lube added periodically) but I would hardly call them troublesome. My wife and myself drove the FD about 10 hours 1 way on vacation this summer. Its not like the delrin make the car unlivable or anything. It does add what amounts to NVH like having super wide tires on your car though. The radio on, or the windows down drowns it out rather easily.
IF I were to do it again... Id go with new OEM or MS Rubbers. However, its not worth it to me to redo them as there arent really any negatives that affect me.
I read something about if you are racing with R comp's the non-give throws the alignment off. I cant speak of that particular poster, though I can say I run 275 wide v710's on all 4 corners at autox and my alignment didnt move anything noticably in the 2 years in between alignments.
OP, depending on your budget and what deals you can and cant get - The delrin arent *bad* in my experience. Just make SURE you put zerks in them and arent buying into the "self lubing" thing. They WILL need lube added periodically. The car will feel much more responsive to steering inputs. This is great on an autox track, a bit un-nerving on a road course. (or maybe thats the autox alignment
) OEM and MS's are pretty expensive, so if you cant afford either or want something stronger I wouldnt be turned off by the delrins. Of course, I also wouldnt be turned off by the poly. (which are apparently hard to get now)
In the end its up to you. I dont think there is a "bad" choice out there. I think youd have a hard time going wrong replacing your bushings with anything newer than 15 years old
