Whats the optimal setup for the upper and lower control arms?
rod ends on the lowers and uppers with super soft bushings?

 

A lot of threads on this subject, you can go the route you're thinking only if you do something to control the top of the rear end, ie. tri-link.

 

im planning on a tri link
Didnt know you needed to do the tri link before the control arm mods though.

 

The Tri-Link takes on the work of the upper control arms. So, if you go with a Tri-Link you will want to modify the upper control at the same time you install it.

Look at what Jim Susco does at G-fForce or at what Paul Yaw has done with the upper control arms.

 

Optimal setup involves relocating the mounting holes on the rear end housing. Besides going though all that, I would say tri-link it, remove the upper arms, get spherical arms for the lower.
