I just need to do more research on where there exist only single axis movement (replace that with delrin) and where there is more (replace that with spherical - SPL is supposedly going to release a whole set soon). though more compliant than poly, i read that delrin still restricts multiple axis rotation to some extent.
if you have any input on which mounts or moving parts move where, i would love to hear it. especially on the front lower arms and anywhere in the rear. im waiting on the spl front arms to come out so i dont have to worrk about the front upper.

Well to be specific, there are some places where multi-axis movement is happening but it shouldn't be for performance. The A arms these bushings go into are a good example. The only axis of movement should be up and down, but the stock rubber bushings allow front-back and in-out movement as well for "ride comfort".

As for compliance the order would be: rubber, poly, delrin or bronze, and ultimately metal-metal bearings. Delrin does not restrict rotation, it allows parts to rotate smoothly when shapes and tolerances are properly engineered.
Poly only allows parts to rotate when it doesn't fit very tight and grease is used.

I guess a comlex diagram would have to be made to show where parts move in a single axis, in multiple axis, and where bushings are being used to simply hold a component in place.
