Update: 3/9/2021
Bushings are paid for and will be hipped from RD Canada soon.
It looks like RD Canada will be adding these to their line soon. I convinced them there is a demand for the rubber bushings with Elephant racing as the only other supplier currently offering them.
I have a jig made up that I think will allow the installation of the bushings without a shop press. I will start a new thread with the details and progress.regress on it. If it works I can lend it out and will share the parts source info. It basically uses a piece of 10mm all thread to pull the shaft through while clamping on the bushings so they do not get pulled into the trailing arm.

Bushings were brought in to Restoration Designs Canada. I will be placing the order as soon as all are paid up. Will send PM's to all who have inquired. Last chance to get in on the group buy.

Shipping will be about $7 per set if ten sets are ordered. We are at ten sets now if everyone who has replied comes through.
Reshipping will be $8.
I prefer Venmo as form of payment as I am doing this at cost. If you are computer challenged I can take a check.
Cost total for softer bushings is $100 and $110 for the harder bushings.
If you want two or more sets deduct $8 from cost of the second set.
Please email me at bdstone914 at AOL dot com with you full name, address, number of sets wanted and hardness.


I am going to order at least one set of real rubber trailing arm bushings from Restoration Designs Europe. They offer a street grade and a stiffer performance grade.
The only other source for rubber trailing arm bushings I know of is Elephant Racing and they are very expensive.
I have requested a quote for shipping on up to 10 sets. The current prices are 69 for the street version and 77 Euros for the performance version.
Rubber bushing are difficult to install but are like the original bushings that add torsional rigidity and adapt to the trailing arm variations.

I am going to get one set of each. The biggest problem I had installing the rubber bushing is that the bushing wanted to push out or scrunch up as the shaft was inserd. I suspect the stiffer bushing may be easier to install.

Here are the links:

Just to be clear that is $83.75 & $93.46 USD, does that $ include Ship and VAT ?
Im interested

Rich,
I am waiting on a quote from them. The web site mentions 21% VAT but i dont think that applies to U.S. customers.
Are you interested in more than one set?

You know I don't need these but I'll be watching and applaud your interest in furthering the 914 groups interests Bruce.

Do you deliver?

In your case yes.
Is that a deal breaker?

I may be, turns out Im paralleling your effort as I have a couple customers in need.
I described that need when I asked about Marks offering HERE

IDK but in prep for my installs I simply take the best shafts I have put them on a lathe and give them a once over. Rarely are that more than .02-.03 out

They’re available from Porsche new

@IronHillRestorations

Are you sure? PET only shows a part number for the complete trailing arm. I know Porsche offers the front A arm bushings for anout $20 each.

Sorry it was early. Fronts are available new. My bad

What is the expected difference to 914 Rubber trailing arm bushings?

I'd love to know more about the expected differences (dimensions, durometer, or bushing rates) either from street to performance or better yet to all other competitors.

I'll need a set but haven't decided on source. You're corect Elephant is very expensive, and more recently I think @bbrock has run into some fittment issues with 914Rubber parts on OEM pivot shafts.

I know I definately don't want to do solid stainless pivots and add more weight for no reason. Would love to see something that works with OEM shafts.

I have a set of Elephant Racing bushing coming on Monday. The price for bushings alone is $200 and they sell the 2 special install tools for $40 each. So $280 for a set without pivot shafts. Quite pricey but as @Superhawk996 said, I just installed a set of 914Rubber bushings last week and they are not acceptable. I probably would have jumped on a GB through RD but I already have these coming and really need to get this done once and for all. This will be the third set of bushings I've installed without using so I would have saved money by just biting the bullet with Elephant in the first place.

Than expected difference is that fit and function like the original rubber bushings. They can adapt to the variation in diameter and lack of linearity of the two holes.
The 914 Rubber bushings are not made of rubber. There is no compression like the rubber. I want to try both durometers with bith the SS 914 Rubber shafts and non straight original shafts. I expect the 85 durometer bushings will be easier to install as they wil have less tendendancy to scrunch up as the shaft enters from inside the trailing arm. I dont think the performace differen e beyween the street and performance bushing will be noticible.

I didn't realize 914Rubber parts wern't rubber. I took a quick look and could see tool marks on them which I had erroneously assumed to be from a mold. I definately don't want Delron or other non-isolating material for my street car. So I guess that only leaves Elephant as the viable option.

I went to the RD links but didn't see any info that differentieated them. Thanks for the info.

Bruce, I'd be down for a set of the 85 duro parts.

@Bdstone914
@bbrock

They list the racing version as 85 shore hardness but do not state the hardness on the street version. I am in email contact with them and will ask.

The 914Rubber offerings are very confusing because they have terrible descriptions on their catalog. They offer TWO different bushing styles. One is a Daystar poly graphite bushing (Item # 99-3015-335). The other was sold and advertised in a group buy as rubber (Item # OEM91433105B) and comparable replacement for OE rubber bushings. I have a set of each and can verify they are very different. The Daystar bushings are semi rigid and install with fitment you would expect of a hard bushing. The rubber bushings are much more flexible and are supposed to install with a friction fit. The problem is that they aren't dimensioned to accommodate the variability in trailing arm IDs. For example on my trailing arms, they fit the inner side with a tight enough squish that they would probably work but are way too loose on the outers. I think 914Rubber tried to get a goldilocks fit that would be easier to install than Elephant, but still provide a proper friction fit. A swing and a miss from what I've seen.

I'm in Bruce, though I am currently undecided on which hardness I'd like to run. Curious as to how much handling gain there is with the "racing" version. There are a few other parts I'd like to get from you in the near future(pedal cluster, late targa latches). Perhaps they can be shipped together once this is all figured out.

I have a set of 914Rubber compliant rubber bushings (or what ever they are) that I got in the group buy, but If I am to have potential issues down the road, I am interested in your rubber bushings from Restoration Design EU Bruce.

I am definitely in for a turn key solution too, i.e. I bring you the rebuilt/re-plated bushingless arms and shaft I got from you a while back, and you press in the rubber bushings ready for the arms to be bolted on...

Bump. See update in initial post.

I'm in for a set of the performance grade...I sent an email with info and Venmo for payment. Thanks, Dave

Email sent per updated OP!

@Montreal914

Sounds like a plan. I have a set of arms that need bushings. If you want the hard bushing I will install the softer ones in the arms I have. Saves me getting another sets of arms powder coated.

Here are the parts I got from you (kind of dusty now... ). Once you are ready, I can drop these off for the bushing install.

Bump with update.

I'll take a set of the harder bushings, please.

@bdstone914 , sending the money via Venmo with my daughter's account. You should receive $110 tonight.

Thank you for organizing this and sorry for the delay...

Bruce, news to me the 914Rubber ones are not made of rubber.
You may be thinking of the old polygraohite ones.
Ours are made of rubber

I bought them and they are not rubber like the originals. They are marked WDG. You list the Daystar on the site and yours with not description. They squeak like the poly material. Check them out.

The polygraphite will squeak.
The not sure why yours would be ones you used an oil to install them.

Bump, order placed. Bushings will be shipped to me soon.

Am I still able to buy bushings? Any available?

@Grego in saC

Sorry but no. Only enough were brought in from Europe to cover pre orders. They should be available from Restoration Designs in Canada as they are adding them to their offering.
