There is a group buy put on by JimLab for another run of the unobtanium
FD suspension bushing kits. These are Nylon 6-6 material which is much stiffer than polyeurathane bushings. I'm under the impression that only MazdaSpeed offers replacement bushings and they are 50% more in cost.

Here is a link to the thread:

And here is what you get for the cost of $675:
4 front upper control arm bushings
4 front lower control arm bushings
4 rear upper control arm bushings
2 rear upper control arm shock mount bushings
2 rear trailing arm bushings
2 differential mount bushings
18 total

There are currently 14 people in. If the number increases to 18 people the cost goes down $20. If you really want your FD to handle this is the ticket to brining it to the next level (with better shocks/springs/sway bars as well). Sloppy worn out bushings happen from 80K miles and later depending upon road conditions/driving habits/climate.

He only makes a few sets at a time and the last run was about a year ago I believe. Everyone says the quality is top notch.

Anyone interested in this contact Jim at jimlab@earthlink.net for payment. This buy ends tomorrow I believe. 3/4/04 (Thursday)

THey are essentially delrin bushings.... made from a nylon rod and then machined. The ones from MazdaSpeed are something like $1K!

FD stuff sure is pricey. My FC polyeurathane bushings were only about $130 for everything including toe eliminator bushings.

Im pretty sure the bushings used in the FD have a fundamental difference preventing the larger poly compaines from mass producing them. Thats probably why they are so expensive.

Yep and parts are getting harder and harder to find, even driving the price up more. Nothing on that car is priced like the FC, and if you get one that needs work, lots of savings out the door.
