I have been looking too. Too late for Unobtainium. There are two sets that Jim is going to auction off...it will be too rich for my blood.

See http://home.earthlink.net/~jimlab/ for more info.

No one else has makes anything for the FD (beyond OEM).

Actually Mazda Competition Parts offers a full bushing replacement. The rubber is 40% stiffer than stock. The downside is the bushings are expensive (charged by the bushing)...in the thousands of dollars to do the whole suspension. Your best bet was the "Unobtanium" group buy.

Why are they no longer selling them?

M2 makes toe links and trailing links for the rear suspension. The toe links are often the cause of a wandering rear end, and the trialing links help prevent wheel hop. They also sell the Mazda Compeitition bushings:

Also, the clunky bushings in the rear suspension are ball joints front the factory, so no aftermarket replacements will probably ever be made (no need). You get the parts (six identical bushings) from Mazdatrix (http://www.mazdatrix.com/), or even the Mazda dealer. I replaced a bunch of these with common hand tools in my driveway and wrote a how-to:

In the Japanease RX7 magazines that I read sometimes, there are companies who make entire polyurethane bushing kits for FD RX7's, can anyone tell us of who can import those? Somebody's gotta know. P.S. What ever happened to the guy who gave Energy Suspension an entire FD RX7 suspansion for R&D so that they could make a Hyperflex kit for it?

Actually the bushings that you normally see in Japanese RX7 magazines are USUALLY made from "stiffened rubber". As for the guy who gave Energy Suspension an entire RX7 suspension....that would be hksfd3s.

I have a new unobtanium set. $500 - see post under 3rd gen parts.

dude...you are pulling old thread just to sell them.
The price is a bit too high, plus your set don't include the differential mount bushing. This is what most people after...

I've got solid links on the front bar now. I've got the toe links and trailing arms on there too. (rear duh)It takes some getting used to as the rear end now is very toutchy. It feels like it is wandering around a bit as you now can feel EVERY movement of the rear suspension that was covered up by the slop in the stock bushings.

Max, We used your write up when I changed my spherical bearings, It was fairly painless and saved a lot of $$ over a shop doing it.
We also noticed for the first time the two braces on the rear suspension on the '94 that the '93s don't have. Kinda cool.
Also up there, Jim's set does not replace the sway bar bushings or the bearings in the rear end, only the rubber ones on the arms and diff.

There is a big aftermarket company developing adjustable bushings. This was explaned to me by a local shop owner. Im not mentioning either name, cause I'm not sure if this is supposed to be public knowlege. Supposedly they will be out shortly, cost a little less than stock bushings and are perminent. Sounds too good to be true, but we will see.

Well i know for a fact its not Prothane or Energy Suspension..

..unless someone stepped up recently and bought the 5-10 thousand full sets required to get them interested to do a run? (and donated the car for however long?)

heh are there even 10,000 FD's left?

I am working on a group buy for Mazdaspeed bushings, but they will still be very, very expensive ie $1500-2k for the full set, motor mounts included most likely - Ill keep you posted to see if theres any interest

Is the sets from Jim the best for road course racing?!

Thanks

If your FD does any street time, I recommend AGAINST using solid bushings. These will absolutely rattle your teeth, and the squeaking will drive you insane. Nuff said. Get the stockers. They work fine and are compliant enough to make street driving bearable!

are you refering to jimlab's bushings?

anyone else using jimlab's bushings and want to leave feedback with respect to noise etc? My worn out stockers are damn loud and I can't imagine it being any worse.

TIA

maxcooper

Jim's bushings made less of a difference than I expected, but they do increase noise and ride harshness a bit. They also require more maintenance (greasing) than you may desire for a street suspension.

The stock bushings that Jim's bushings replace are unlikely to be noisy. It is more likely that you have bad pillow ***** and/or toe links, which are not replaced by the Unobtanium kit.

been there, done that with the help of your site of course!
Even built new SS and aluminum toe links. i've been putting this part off however, due to the rather large expense.

were your stock bushings in bad shape? mine are the originals with 135k miles on them, so they are due. I would assume that coming from a decent set of bushings might not make a big difference, but I am hoping they help considerably on my car.

most of the "negative" feedback that I have been reading seems to be associated with the differential bushings. can you tell if that is were the increased niose is coming from? I'm thinking of using stockers or fabbing up a stiff polyurethane bushing (shore A 90 or 95) for that, but am still doing some research.

maxcooper

I did not install the diff bushings, so that isn't a factor on my car. The Unobtanium bushings made less of a difference than I expected in terms of noise and ride comfort, but they do have some effect.

I thought that you meant not a big difference in terms of performance. thanks for clearing that up.
