What are suspension bushes for anyway?
Suspension bushes are fitted to cars at all points where the vehicle chassis is joined to a moving suspension component. They are fitted to provide a noise and vibration absorbing barrier between the road and you.
Why are they made of rubber?
Rubber acts as that sound barrier, damping out noise and vibration. Without them cars would feel much harsher and noisier. Rubber is also very very cheap.
Do racing cars have rubber bushes?
In general the answer is no. A lot of racing cars, especially single seater track based cars use metal joints which do not provide any noise absorbing. The life of these joints is measured in hours. They are not suitable for road use. However a huge number of racing cars still use rubber bushes. These are either production based cars adapted for race use or rally cars where the forces on the suspension can be so high that metal joints would break.
Can I fit POWERFLEX bushes to my racing car?
If your race car has rubber bushes anywhere in the suspension then fitting POWERFLEX bushes will improve all aspects of it's handling. They will outlast rubber by a factor of ten. They will control the geometry much more accurately during rapid suspension movements and they will reduce tyre wear.
Why not Nylon bushes?
Nylon is probably the worst of all worlds. When a suspension arm moves up and down it does not move only up and down but describes an arc. This means that, for example an inner track control arm bush will be required to flex in two dimensions at the same time. In this example a metal bush will allow this movement as will a rubber or POWERFLEX bush. However a nylon bush will allow up and down movement but 100% of the arc loadings will be transferred into the arm and the chassis. This causes arm flexing and can easily cause premature arm failure! Of course nylon has no vibration absorbing characteristics at all, so all vibration is transferred up the already highly stressed arm
this is on my to do list aswell...

"Better ride" I wouldn't necessarily agree with. The standard bushes will give a better ride in terms of comfort, but for tightening things up and getting rid of "give" around the various componentry in the suspension system the uprated bushes will help. I've just got a pair of front ARB bushes in "race" spec, which means they're very hard, but I only got them so hard because they won't act as directly as the wishbone bushes etc, so I won't have a rigid ride in the car. Don't go thinking "oooh I'll get the hardest ones out there, my car'll go round corners really well then" unless you're prepared to sacrifice comfort and a non-rattling interior!
