I don't know anything about the materials except for ES's advertising ploy, but experience has shown me (es masterkit) that poly bushings wear badly. The design allows rotation in only one axis, any force attempting to move the bar in other directions will lead to wear. Not many bushings in the DA/DC suspension which only rotate in one axis. Eventually the tight fitting hole in the centre of the poly bushing will oval and your performance will spiral downward.

Exactly locating the suspension members is critical to performance. OEM bushings, whilst arguable not as durable, are designed to allow and accept the correct suspension movement and will maintain geometry for longer.

If you're bushings are so shot that you can wobble the control arms around, and you only plan to have the car for a little while longer, then it's a cheap fix. If you're a purist and have serious goals about performance, then you'll probably end up like me, dreaming about sphericals instead.

Search for "HardRace". I believe they make stiffer rubber [or maybe poly] bushings in the style of OEM. At a guess they'd be priced somewhere between ES and OEM.
