There are benefits. Polyurethane bushings will essentially never wear out, never compress, never get soft. If you like a firmer ride you will love them and it will tighten up the front end, but the real gains in performance are at the back. poly bushings in the rear end is life changing. Best single suspension modification you can make.

I was asking from the handling view.I am little surprise that there is no gain in handling by changing the front ones but only the rears...
But if you say so you will know something..

Where do you get a firmer and harsher ride from??? I picked up an even more ridged set up with spherical bearings for my front control arms... There was no difference in ride harshness/firmness or even noise....

Tight front suspension set up really helps improve steering response, feedback, repeatability....

I like this. Funny thing is, i've never done rear end work like that before. I suck suck suck and can't find poly bushings for rear online, in kelowna at all.

Personal preference I guess. The roads in Edmonton are an absolute atrocity. Even the good roads with no actual potholes are not smooth at all.

As far as I know mine and SuperPro are the only options for rear poly. I have tried to get a second group buy going a few times with no luck. I honestly don't think it's ever going to happen again.

Id be interested in a complete kit.. but would you be able to direct me in the direction of this rear poly kit?

I had someone turn down some off the shelf ES bushings for the rear TTL's

I didnt read through this whole thread, so I dont know if it was ever clarified but, The ZX2 bushing kit will fit the following cars: 90-94 323/Protege, all Escorts from 91-03, and MX3's with the small front control arm bracket, and how do I know? I used to run MX3 front control arms on my car.

The only things that differ from certain cars and models is the ability to use the swaybar bushings/endlinks, and the steering rack bushings will not fit the Mazdas.

There is also a poly shift stabilizer bushing available, and unless the MX3 uses a different diameter one, that should fit as well.

Even if there was no performance enhancement from the bushings, it worth replacing them just for the fact they wont wear out or get destroyed from oil leaking on them.
