Rear control arm bushings..where poly, where rubber?

[87gninpa]

Have a nice set of rear control arms to replace my 200k stockers. Question is, I have heard of binding in the rear on a street car if the right combo of bushings is not used. I have the UMI tubular setup (non-adj) and am wondering whats the best way to go. A combo of both? all rubber? all poly? Any input appreciated, especially experience. Also, car will be almost 100% street driven TIA

Poly front, rubber rear, IMHO.

How big of a PITA would it be to get the poly bushings out of the new arms and replace with rubber?
