We are in the process of doing the A arm bushings in rubber
We can easily do these up in a polyurethane at the same time, just have to do enough to pay for the materials and set up would be looking at 25 sets to do the Poly

The GB would be for a set of 4 (enough for 1car)

For $28 in rubber

and $36 in poly

To get the pricing right we need 40 takers in rubber and 25 in Poly


We've been in testing on these for some time and had made a couple variations.
This is what they look like.

SO Who's in?

do you mean trailing arm bushings? I already bought the kit so will the shaft be the same? Will these squeak after a while?
Thanks

Posted by: mepstein Nov 18 2019, 08:02 PM

Mark - how do these differ from the previous ones. Thanks

Posted by: Mikey914 Nov 18 2019, 09:01 PM

Previous ones were the self lubricating Poly-graphite we did not make them. The feedback from Eric was that we needed to make these to do exactly what factory ones did, he was mentioning that there was some squeak from them as they needed to be lubricated, as the rubber ones were not. There is some room for improvement that we will be doing also.

Posted by: Mikey914 Nov 18 2019, 09:04 PM

The shaft kit will be the same. The stainless is bulletproof.
I was amazed to see the factory was a hollow tube and the welds were not great. So water got in the inside and rusted.

I'll help support the cause. One set please.

Posted by: Mendivil26 Nov 19 2019, 10:26 AM

Count me in, one set for me please

Posted by: Retroracer Nov 19 2019, 10:32 AM

I'll take one set please; rubber.

Poly compound is CRITICAL. Interested for sure but how will we get the right balance of compliance and firmness?

Genuine question / don’t know how to do that and haven’t tried to make bushings before.

One set in rubber please...Thanks

Posted by: Tdskip Nov 19 2019, 03:24 PM

Well alright then!

Posted by: MM1 Nov 19 2019, 03:29 PM

I’m in for one rear set in rubber. . .

and one front set in rubber (add on?)!

Posted by: bdstone914 Nov 19 2019, 05:03 PM

@http://www.914world.com/bbs2/index.php?showuser=3348

Are the shafts going to be offered in a bundle deal?

I have found most original shafts are not straight which makes bushing installation very difficult.

I have done several sets of the Elephant Racing sets and the installation is tricky.

Good installation tools are a must.

I added tapers to the Elephant tools. Delrin might be more slippery and better.

I have a couple clean blasted trailing arms and would be willing to install them.

I also have sets of used shafts for test installation.

I am betting the new shafts will make installation much easier.

Posted by: Mikey914 Nov 20 2019, 11:04 AM

Thanks Bruce,
We have actually installed in the shop and had our 1st non commercial customer do an install. His shafts were shot so he also used the stainless shafts.
@http://www.914world.com/bbs2/index.php?showuser=22336
I personally found these much easier than the front. And yes I need to change the title as it's confusing. But A arm bushings will also be on special.

Anything you want to add?

One rear set in rubber please...Thanks

Posted by: tvdinnerbythepool Nov 20 2019, 08:18 PM

The install of the bushings was VERY easy! The original rubber was deteriorating/cracking, stiff and definitely past it's better days. Getting those out was the most time consuming part but not too bad.

The stainless shafts matched the rubber bushings really nicely. They are a little heavier than stock but far superior craftsman ship. Pressed nicely into the bushings with my little shop press.

My Original Shafts were toast, deep rust pits and threads were toast.

Would definitely recommend both the shafts and bushings from @http://www.914world.com/bbs2/index.php?showuser=3348

1 Rubber Set plz.

Posted by: pete000 Nov 20 2019, 10:17 PM

I would be in for a set of the rubber rear bushings, The stainless shafts are just too heavy for me. The factory shafts are hollow and half the weight as long as they are not rotten...

Posted by: bbrock Nov 21 2019, 08:31 AM

Well, shoot. I have a set of as yet, unused poly-graphite from the first GB but always wanted rubber so I'm in for a set.

I'd like to hear a bit more about the installation though. Seems like if the tolerances are OEM, then some cussing should be required to get them in much like the fronts.

Posted by: TonyA Nov 21 2019, 08:44 AM

put me in for two sets for two cars both front and rear

Posted by: jc73-914 Nov 21 2019, 09:08 AM

I'd like to take a set pls. Rubber bushings + shaft, thx.

Posted by: Highland Nov 21 2019, 09:25 AM

I too would like to be added for a rubber set

Posted by: jsaum Nov 21 2019, 09:37 AM

I’ll take a set of the rubber bushings. Possibly the shafts once I see the prices.

Posted by: Mark Henry Nov 21 2019, 08:59 PM

Not sure if I want rubber or poly? new shafts?
This is about the only job I haven't done because I don't have any issues.
If you do poly is there a way of adding grease fittings?

I have Full Motion (needle bearings) on the fronts.
Hot street car only, I might do a DE now that I'm a PCA member.

Posted by: Mark Henry Nov 21 2019, 09:07 PM

I can't find the shaft on your site

Posted by: Literati914 Dec 1 2019, 12:36 AM

'cause they're not going to be available 'til end of Dec?

..So - as for the current A-arm bushings on the site, they say "NEW" but have no mention in the description of what they are made of (tho the tool is described as delrin). So I'm confused again, are these the latest iteration new rubber that the rear trailing arm bushings are GOING to be offered in? And are the current rears on the site (which also have no description of material composition) an "old" version?

Just trying to put together an order for the current sale and not wanting to purchase soon to be outdated parts by mistake.

Posted by: Can-Am Dec 1 2019, 09:51 AM

I'd like a set of rubber ones for the rear if I'm not too late. Thanks

Posted by: bbrock Dec 1 2019, 10:06 AM

I bought a pair of their SS shafts in the GB for poly graphite bushings at least a year ago, so they've been available for quite awhile. I don't see them on either the new or old web site though.

Posted by: Mikey914 Dec 2 2019, 12:21 AM

The "OLD" material is a poly-graphite, we are making a OEM version with an option for urethane if we have enough interest. So far I'm not seeing it we can bring in a multitude of compounds so I'm sure we could make a great product, but at the small quantity we will be using it will be at a premium, so unless we have enough interest it will not pencil out.


At this point the OEM version has held up very well for many years, so we will definitely be making these.

Posted by: Mikey914 Dec 9 2019, 02:08 AM

These will be ready soon. Still not seeing enough demand to do the Poly. I have to bring in a min 50lbs of material. For the cost it's not penciling out at this time.

I would take a set of poly

Posted by: Mark Henry Dec 9 2019, 12:18 PM

I see you haven't shipped my "Black Friday" order yet, can you hold it till these are ready?

I'll take a poly set, but if you don't have the numbers I'll take the OE set.

Posted by: Mikey914 Dec 10 2019, 12:36 AM

I'll check with Scott, but he has got very good at getting stuff out fast. I'll let you know tomorrow.
Mark

Posted by: Porschef Dec 10 2019, 05:55 AM

Otherwise a set of rubber if not.

Posted by: Mikey914 Dec 11 2019, 12:25 AM

I did get ahold of Scott and we did get it held.
Mark

Posted by: Mikey914 Dec 17 2019, 06:12 PM

These are running this week, Didn't generate enough interest to do the urethane. We can revisit them if there is enough interest, just can't justify bringing in the material.

PM's to follow shortly.

Posted by: maf914 Dec 19 2019, 08:02 AM

I'll take a set of rubber bushings. Thanks as usual.

And a set of poly if you do them. And they don't squeak!

Posted by: soccerplyr Dec 19 2019, 08:56 PM

I'll take a rubber set, if not too late.

Posted by: yellowporky Dec 19 2019, 10:40 PM

I will take a set of rubber front and rear too please

Posted by: Mikey914 Dec 22 2019, 10:15 AM

These are finally finishing up this weekend and I'll be sending PM's out shortly. Just have a holiday party I need to get ready for today. But finally done

Posted by: Mikey914 Dec 23 2019, 02:40 PM

Got we finished these for a little less than we projected GB price is being reduced accordingly.


Merry Christmas to all that wanted these, Still putting together the PM with another little special for ya!

Posted by: JamesM Dec 23 2019, 07:20 PM

My issue with poly bushings isnt with the firmness, its that none of the bushing surfaces were designed to be friction surfaces. The rubber bushings are completely immobile and bound to the control arm/chassis. All control arm movement is the result of the bushing flexing. None of the surfaces on either side of the bushing remotely resemble anything close to flat and or smooth which results in unpredictable (and thus uncomfortable) bushing movement when replacing with poly. Not to mention potential binding/chassis damage BTDT. This is why all the good solid bushings (Rebel, Elephant, etc) sleeve everything and run the bushing on the machined sleeves. I was blown away at how much more comfortable the ride in my autox car became when I replaced my front poly bushings with the Rebel Racing solid bushings despite having gone from poly to a much harder setup. The smoothness of the control arm movement seemed to make a much larger difference in ride quality (and handling) than the firmness of the bushing material.


Was talking with Eric about this exact thing the other day, but one idea I have been wanting to attempt is to run dual poly bushings instead of a single one. Basically take 2 bushing and machine the inside of one and the outside of the other so they fit together where the single bushing would normally install. This would basically move all friction surfaces to be between the machined poly bushings. My only concern at that point is if the material is strong enough at that thickness. This is something I have seen Powerflex do with a lot of their bushings (I even run some on one of my BMWs like this), they also use that to then tune the ride quality by offering varying harnesses for one of the 2 bushings.

No idea how it would turn out, but if you are going to make some polys i think its worth a shot to try it given straight single poly bushing on a 914 are crap. I speak with first hand knowledge on this as binding poly bushings were responsible for breaking one of my front control arms and tearing a crack in my chassis.

Posted by: JamesM Dec 23 2019, 07:24 PM

To illustrate what i am talking about. something like this...

Posted by: Mikey914 Dec 24 2019, 05:38 PM

That's a 911 bushing, they are different. I'm hesitant to redesign this with just a change of a bushing. The factory spent a lot of time and energy making these, and there wasn't a superseded part. That means they were the best balance of performance and economy for at least a daily driver. We can make a shaft that utilizes a bearing to allow rotation. Could use either poly or natural rubber. Considering the OEM rubber lasted 30 years + the difference between the 2 is nominal, again if we can get at least 25 sets, I'll gladly do them.

Do look for the bearing option for the shafts . I'll delay this till next week as we will be running them shortly. So for non binding shaft please indicate your interest we will run 10 sets like this.

Mark

Posted by: yellowporky Dec 25 2019, 08:50 PM

I would be interested in the non binding set

Posted by: gandalf_025 Dec 26 2019, 11:13 AM

I'm in for a set of rubber if this is still available..

Posted by: 914sgofast2 Dec 26 2019, 01:16 PM

I will take a set of the rubber style bushings.

Posted by: Porschef Dec 31 2019, 10:19 AM

Well here it is the 31st and I haven’t placed my order as yet.

I’d like to replace all the suspension bushings on the car, if you’ve not gotten enough participation in the poly group then rubber is fine. Actually, I’d go with rubber.

I’m in the middle of an emergency hot water heater replacement, so pardon my not taking the time to figure this out

Thanks,

Joe

Posted by: Mikey914 Dec 31 2019, 12:03 PM

No problem,
With everything going on I will send this next year (tomorrow).

I'll also extend the plug GB so those that were holding off can get at the same time.

Also, we are giving a special price for all the takers of the rear bushings on the A arm bushings so it will make it a really great deal.

Posted by: TonyA Dec 31 2019, 01:33 PM

Thanks looking forward to you PM on this. Hey do you have all the sway bar bushings I could not find on your website

Posted by: Montreal914 Dec 31 2019, 06:19 PM

If there is still time for the rubber bushing group buy, I would be in!
Thank you and happy new year

Posted by: Mikey914 Dec 31 2019, 06:47 PM

Yes, there is. I'll PM when I can get some time.
Thanks all and Happy New Year!

Posted by: relentless Dec 31 2019, 08:01 PM

I'm in for rubber if it's still ok. Happy New Year!

What's the special on the a-arms?

Posted by: Mark Henry Jan 1 2020, 11:56 AM

I guess you didn't hold it for the bushings, I just got a shipping notice.
So I guess I'm out till I actually need to do this job.

Posted by: Literati914 Jan 5 2020, 06:40 PM

I never got a PM on these, have they already been sent?

Posted by: injunmort Jan 5 2020, 07:52 PM

I didn't get a pm either. hey joe, maybe the focus of the first tech session?

Posted by: Porschef Jan 6 2020, 12:23 PM

Great idea

Posted by: wes Jan 6 2020, 12:54 PM

I’d like a set in rubber if not too late. Thanks!

Posted by: mbseto Jan 6 2020, 01:04 PM

Also in for a set in rubber if it is not too late!

Posted by: Mikey914 Jan 8 2020, 01:19 AM

Not too late on these. Just sent PMs to all.

I got side tracked with making a new option to the solid stainless pivot shafts.

For those looking for the stock ones they are here -
https://900designs-container.zoeysite.com/914/914-rear-axle/501-00-rear-axle

For some reason it comes up in the diagram section but will not be found in the search so I'll look into it.
Thanks to all that have made this possible. The GB will be open til end of the month.

Posted by: Chris914n6 Jan 16 2020, 02:14 PM

I could use a set of rubber rear bushings. Sounds better than re-greasing the poly (pun intended)

Posted by: flmont Jan 16 2020, 11:03 PM

I would have a set also..

Posted by: Mikey914 Jan 17 2020, 10:26 AM

Hey guys,
I’ll keep the GB open, may be a day or two before I can send the codes. Had
D to got to SAN to drive to a Yuma. The father-in-law isn’t doing so well so had to go with the wife to take care of family stuff.
