Have 2000 2.5 L non M z3

I have been studying the problem of which FCAB to put into the z3. Got new control arms, struts, strut mounts ect.
Was going to go with PU on the soft end but it appears that 80a is the softest I can find.
Then I see that there are solid rubber ones (from the M3) that don't have the thin webbing in the middle.

I see that Moog makes some kind of one but I cant seem to find an end view pic to see if it has web or if it is solid.

Is there a PU one that would be as soft as solid rubber ? I like the oil resistance of PU- but I don't mind rubber if it is
mostly or all solid.

Hoping yall could recommend a specific model and brand. It will be a sunday driver but I think I would like a bit firmer than the stock bush
but still have some give---
