Subframe Bushing

and these will work?

I'd say its worth a shot, plus if the z31 is the SAME I'd expect it to

Yeah, that's pretty much true... it's worth a try.

as soon as I get an r200 rear I'll check it out

I have a set of those on their way here. Will get them before friday, or so I was promised.

The bad thing with those is that you will have to reuse the metall slave surrounding the stock bushings. Not a big problem if yours are not rusted away. Mine are so I also ordered a set of stock bushings to take the sleave from.

Hope this fits.

Looks good, so you just burn the rubber centre out and reuse the metal sleeve ay? That makes replacement about 10x easier i think.

Yes, they work. And yes, you just burn the old rubber bushing out and leave the metal sleeve. It can still be a challenge though. When burning the old rubber out, don't bother with Propane, it will take forever. Get yourself some MAPP gas, and you'll have it out in no time. Also, put the new bushings in the freezer for a day or so before the install. That will help shrink them enough that they might just slip in with ease.

Sweeet.....
Driving impressions?

Well, I'm actually currently using solid aluminum subframe bushings made for a Z31. Definitely a more positive feeling from the rearend. Coming out of corners, the car feels more planted, so I'm able to get on the gas a little sooner. It's not as squirmy and generally easier to tell what is going on back there. I think it did amplify the fact that I need stiffer springs in the rear though. LOL The poly bushings should have a similar affect.

I need both the bushes and stiffer rear springs :(

I got my busnings today but I am somewhat confused. I have been told by the place I bought them from that I will need the metall sleave. So I also orderd a set of stock bushings that I was going to burn out and use the sleave.

With the bushing there was a intallation note.This is a bit of it

"Remove the entire bushing included the outer metall shell from both ends of subframe. The bushing can be pressed out with a hydraulic press or cut out with hacksaw. To remove with hacksaw,feed the blade thru the opening in the rubber and reatach to hadle. Saw thru the rubber until the center sleeve can be removed. Now saw thru one side of the outer steel shell without cutting into the subframe. Once you have sawed thru the shell the tension will be released and the shell can be removed from the subframe."

If I understood this correctly I don't need to use the outer shell. I tryed to install them and they fit niceley without the shell. It almost looks imposible to install with the shell.

Hmm what to do?

Well whatever u do let us know so i can be sure they are good an order some asap :)
Also i guess Z31 IRS control arm bushes are the same as S12 to ay?
I have a bit of movement in my rear end and although i'm mostly blaming the subframe bushes i'm sure the control arms could do with a freshen up to. Then i gots to get me some springs.

Yes, I am currently using Z31 poly rear control arm bushings in my S12.

As for the rear subframe bushings, I would really think you need that outer metal sleeve. You might give the company a call to confirm. Seems odd to remove it.

I think you missunderstood me. The polyurethane bushings have no metal sleeve. So I was told to use the metall sleeve that is arround the stock bushing and put the poly bushings inside it.

I have called back and it was comfirmed that I don't need the metal sleeve.

The bushings are now on my subframe. No problem installing them, didn't need a press or anything. I just needed the super grease that was included. Also installed the control arm bushings.

I love it when everything fits so niceley.

Well if thats the case it sounds like time for me to order some :)
Also with the control arm bushes they aren't steel cased or anything annoying like that are they?
I hate removing steel cased bushings.

The control arm bushings also have the inner and outer metal sleeves. You will need to save both peices to reuse with the new bushings. The control arms took some work to put the new bushings in. Liberal use of hot and cold were necessary, although some were easier than others. The bushings came with installation instructions.

If the sleeves are reused then the outer metal sleeve will not have to be removed from the control arm.
Makes it alot easier than removing the metal sleeve in my humble opinion.

When I did it I burned the stock bushings out and didn't remove the metall sleave.
The poly bushings where really easy to put in....in my case.

If you call zcarparts talk to Sam (203) I have alredy talked to him a milion of times so he knows exacly what it's about.

Makes it alot easier than removing the metal sleeve in my humble opinion. Way easier!

Zman - That's great that everything slipped in so easy for you. I hope that's true for most people. I wish it had been true for me. To be honest, I really only had problems with one control arm. The bushings for the other one went in nice and smooth.

Spooled- I was warned from friends that I was going to have a hell of a time getting them into place. So I was/am a bit affraid that they might be too loose and the control arms will start moving around after a bit of driving. We'll see I pray for the better.

Did you use a torch to heat the control arm, and leave the bushings in the freezer overnight? By using that technique, I was able to just pop the bushings into place on one of my control arms. After the bushings cooled down, it was a nice, tight fit. The other side took more coaxing than just hot and cold.

I did nothing. Just put some grease on them and they sliped right in

Huh - I also got my control arm bushings from zcarparts.com Did the packaging say the bushings were for an 84-89 300ZX? I don't think mine would have slid in with just some grease. But I didn't try it either. I know they wouldn't have on the control arm I had all the trouble with.

Yea they are for the Z31. I tryed to install them without the grease first but it wasn't to easy.
Stop scaring me....I'm going to have nightmares about he loosing my subframe or something.

BAHAHAHAHA No worries. If you couldn't do it without the grease, I'm sure they're just fine. I wish mine had been that easy!

Going to order some bushes today :) hopefully postage doesn't kill me hehe.

Okies got my subframe bushes in (havn't done my control arms yet)
Turns out i did have to remove the metal sleeves but thats pretty easy with a die grinder.
They are thick bastards, thicker than stock bushes, lower plate bends a bit when you torque it all up.
Also the crush tube is short as, only 3/4 the length of the total bush, seems to work fine tho.

Bushes installed.

The original bushes ROAWR!!!

Are those subframe bushings pressed in all the way? Way are they sticking out so far? The stock subframe bushings sit flush with the subframe. Are they supposed to be like that?

yup they stick out alot, yes i did install them properly, the factory bushes do sit flush but remember they have those rubber rimmed plates that sit above them, yes those bushes are still fatter than stock but they fit and are nice and solid so i'm happy.

just to clarify. these bushings work on all s12's correct? cause if thats the case then i will definatly order some.

they worked on my S12, not a perfect fit but they fit, i'd be interested to see how they fit on a Z31, weather they are perfect or not.

Neb, let us know if you notice a difference! If you dont notice jack then i think ill give this mod a miss!

On the road i can feel a bit more vibration coming into the car, hopefully it'll stop my rear tyres shifting far enough in the rear guards to touch the font of the guard during drift :|.
I will tell you how it goes but the stock bushes are quite small and soft, it's got to be an essential drift mod me thinks.
I'm also doing the control arms.
