Spherical bearings in ANY pivot on the rear of our cars is an absolutely huge upgrade. On an S14 with Z32 uprights it's basically a necessity from the high angle. If you run your car very low, you might need to slightly file the upright itself(the angle gets worse with travel), but they're a huge upgrade that you can immediately feel. Think about it, it'd be like going from a 20 lb wheel to a 13 wheel right there - absolutely huge.

Sphericals in all the other suspension pivots just let the suspension move without binding. With spherical bearings you can move the rear suspension up and down with one hand(without the coilover on there of course) - it's that low friction. Try that with rubber bushings, or even worse, polyurethane.
