Rear control arms are definitely a suspension upgrade you are going to what to do. Unfortunately there are so many to choose from it is easy to make a mistake.

We manufacture several types of control arms using different bushing/bearing combinations at the pivot points. This includes bushings such as rubber, polyurethane, Del-a-lum, or spherical bearings that provide the best control with no resistance to movement or pivot. We use combinations in order to achieve specific goals

Why not use just polyurethane?
Polyurethane bushings do have there place, however it depends upon what you are going to do with the car. The issue we have with just using polyurethane, is that unless you are drag racing, polyurethane restricts the movement up the rear suspension. The rear suspension can not articulate. This creates rear suspension handling problems and causes the car to have less traction on corner exit and  ride rough over bumps. Most people notice the ride change. The only way we have found to provide rear suspension performance suitable for handling and performance street driving is by using a spherical bearing at the frame side and our Del-a-lum bushing on the rear end side.
The aircraft spherical bearing allows rear end articulation without bind and the Del-a-lum bushing
controls defection. The result is smooth suspension movement without bind or defection. We have proven
this concept time and time again on the race track and street applications. Therefore, we offer three
different control arms for your application. We offer polyurethane control arms just like all the rest.
(Recommended for drag racing only). 2nd we offer a spherical bearing (frame side) and polyurethane
(rear end side) control arm for the street. 3rd we offer a spherical bearing with a Del-a lum bushing as
the ultimate control arm used in all applications. This would be the best choice. Note: Almost all of the
other manufactures of rear lower control arms use polyurethane bushings. While we offer polyurethane
control arms also, our primary reason for using them is to be competitive in the industry. However,
polyurethane bushings create a tremendous amount of bind for street and handling applications.
We will not recommend polyurethane bushed rear control arms for street or handling applications.
