Stupid question about delrin bushings (ISC front UCA offset)
So I'm trying to put in a set of ISC front UCA offset bushings to add camber. Following their instructions (http://www.iscracing.net/bushinst.html), I got the bushings in, slid the long bolt through, put them in the car, and tightened it down and the control arm binds. Checked the gaps and (leaving out the factory inner washers) there is clearance between the bushing and all of the non-rotating surfaces (outer washers, the ends of the tube on the subframe).
So, stupid question time:
Do these need lube or not? Googling seems to be unclear -- lots of people asking, nothing definitive one way or the other. A bunch of references to delrin being "self-lubing"? No lube included in the ISC package, none mentioned in the instructions. They come with zerk fittings, are those just for location, or also for lube access?

I made my own Delrin offset bushings and they definately needed to be lubed. If they included zerk fittings I'd say ISC thinks so too.
It also appears from ISC's instructions that you have to ream the busing bores to size after you install the bushings in the control arms.
You should be able to just barely turn the sleeves in the bushings by hand and there shouldn't be any slop.

You need to open up the Delrin hole sightly to allow the metal sleeve to slide into the bushing. Be
sure not to make it too loose.

You can buy bushings that do not require lube, in the heavy equipment industry they are starting to go this route. The metal bushing and pins are pre-impregnated with oil, its cool stuff.
