Hello, am about to install new shocks and springs into my AU3 XR8 (Konis and Kings).

At the same time I will be swapping my diff...is cactus.

My question is in relation to the REAR IRS suspension:-

Has anyone installed Urethane (Noltec, Nolathane, etc) bushes onto the Upper and/or Lower REAR control arms ??
If so why and what was the outcome ?

Any advice/comment appreciated.

In conjuction with the shockes and springs the front will get Noltec bushes in the Lower Control Arms as well as a Noltec Camber Kit (I picked up a spare set of arms and have pressed out the old and pressed in the new bushes...these are ready to go).
