I did the complete poly setup on my '88. I'll never do that again. Even the poly graphite ones squeaked on speed bumps and rough roads from the get go and it road terribly. The ride part was liveable, but it made the car much less fun to drive.
If you have good rubber bushings in there, I wouldn't even consider it. There's not that much of a difference as far as handling goes. Nothing the average driver would see without being very, very familiar with their car on the track.
If I had worn out rubber bushings, it may be worth it, although, personally, I'd just replace them with new rubber ones.

You have to make sure you thoroughly grease the poly bushings before installing them, or they will squeak. The feel won't have the "give" of rubber - IMO, that is a good thing. I like to feel the road, it gives me more feedback on what the car is doing.
On my old Talon, I had poly bushings that survived the destruction of one car after about four years, then spent another four years in another Talon. They looked like new when I parted out the second car. My 2000 Jeep Cherokee has rubber bushings that are already starting to crack.

Another big advantage of poly in the front bushings is installation.
With rubber, you need to torque with full weight sitting on them.
Poly works like a hinge and end bolts can be torqued prior to
install. It sounds minor, unless you find you need to pull
the radiator and shroud to get at them with a torque wrench.
Often people have squeaky sway bar bushings (easily lubed) and blame the control arm bushings.

I replaced with Urethane Bushings. Now it handles too stiff and responsive for my usage. Ill switch back to rubber Next time I do Ball Joints.
ALSO..Be extra careful If you do use The Poly's Be sure to use LOCK WASHERS with the Control arm Fasters. This is not necessary with rubber bushings because they compress. Poly's Dont compress , the Nut can loosen and upper control arm can drop out.
