I have been on them all ... rear axle bushes been on worn standards, new standards, LCR axle bushes .. finaly to super-pro rear axle bushes. If i was you i would skip the rest and go straight to super-pro's.
I did the same for control arms, i ran them in all specs .... standard arms standard bushes, to standard arms with r32 solid bushes, to r32 arms with standard r32 bushes, to r32 arms with defcon inserts front bush + super-pro caster adjuster bush rear.
If you want maximum comfort but better than standard then go for LCR top mounts, LCR axle bushes and standard r32 bushes in the r32 arms. Personaly i would just go straight to super-pro as they are still plenty comfy enough but give the best handling.
I run LCR top mounts as they last me 3 x as long as standard top mounts .... i have some 034 motorsport top mounts to try next ... they are still rubber but even stiffer than LCR mounts.
