What is the final word on this? None of the answers seem to be in agreeance, which style will allow for the best weight transfer between poly and rubber?
Now I need to pin those needles, got to feel that heat

I have poly up front on mine. I just made sure my UCA bushings move freely to get weight transfer. They tend to be tight.
Been 1.320 sixty foot w/ Cal-Tracs on radials.

So nobody has any experience with Nylon/teflon LCA bushings VS poly?
I'm using Delrin (nylon), poly is, IMo only a short term improvement over rubber, before it craps out, it really has, again IMo, a short useful life, and that that bothers me, as it has little warning before failure. I'm making my own Delrin to replace poly where I can.
I'm with Helmuth Hübener, and no soup is being served today.

So I am assuming you're making ALL of your nylon stuff, right? I don't find where nylon is available for Mopars and no user feedback anywhere, either.

There is no ONE answer for every car. The more power the car has, the less it has to rely on pitch rotation to make the car work, so a loosey goosey front with lots of travel is not needed.
One of the BIGGEST problems guys have now making their cars work, is that the fronts are TOO loose. They still think all that stuff that needed to be done in the 60s to make cars work on junk tracks, with junk tires, still applys today.......Not the case

I'll take too loose and slow it down with shocks as opposed to too tight.
