Just a few basic questions:

1) Do the rubber bushings I circled need to be changed? None are cracked or damaged, but are they just spacers or do they affect how tightly the car handles?

2) Plan on replacing shocks with Bilstein shocks. Can I reuse the top hardware shown or must I acquire new parts? If so, where would one purchase said parts?

3) Is there a recommendation for a rear trailing arm rebuilder in the San Diego area? I need new rubber bushings, new bearings, and my hubs pressed back in. I know many do it themselves, but after reading some of the recent posts I'm a bit intimidated. (IMG:style_emoticons/default/unsure.gif)

I am pretty sure that you will get those bushings with the new shocks.

Nothing comes with rear shocks. Reuse everything.

Like mark said, reuse it. New shocks only include a top nut and a clip for the lower spring cup. You will need the cups that hold the springs for the Billys. Give Bdstone a ring, he usually has a pair. think they are around $60 each new.

Edit - some of the Billsteins include the lower cup, some don't but great shocks.

I am almost positive my rear koni sports came with the cups and bushings. But that was a long time ago..

usually the bushings are good, and only gas shocks are available so do not need the shock pillow, hence rear Bilstein shocks and new factory duplicate rear springs

Thanks for the information. Just a couple more questions:

1) I bought the car non-op so never really drove it. If I grab the rear wheels and try
to wiggle them they are solid. Should I just leave the original bearings alone or is it still recommended to swap for new bearings since I have the arms out?

2) Which ones are the shock pillows?

3) Is Elephant Racing the only option for rubber bushings? They're the only one I can find.

Here's a video which covers what gets reused...with a coilover setup anyway!

I just received a pair of new rear Bilsteins on Saturday. Here is what you get in the box: Shock, locking nut, 2 washers, a lower spring perch. There is also a circlip on the bottom ring that can be moved to adjust the lower perch location.

I have a spare set of arms I can build for you and then you can just swap them out.

Hey bbrok, are those Bilstein B6 Performance Series Shocks and Struts 24-001793?

I was going to get a pair from Summit unless someone else can recommend a better seller.

https://www.summitracing.com/parts/bsn-24-001793

Also I know 914 Rubber offers 100 lb rear springs, but I haven't been able to find springs anywhere else of differing rates (not coilover).

Yes. B6. I got them from PMB Performance.

We make the parts you are looking for. We are also in the process of making the rubber trailing are bushings and we are working on a set of new shocks that will be matched to the springs that we have now.
Here is where you can find the parts on the new site.

Ditto. I have a set of your poly bushings and SS pivot rod which I could be installing as soon as next week, but will hold off if these rubber bushings will be coming out soon.

I purchased trailing arm bushings from 914rubber last year. They came with the steel shaft.

Prototype version 2 will be done in the next few weeks. They need to be test fitted at that point before we go forward on the production run. I believe we have it dialed in at this point and the prototypes will be great. We most likely will have a few extra that Mark may be persuaded to let go for R&D on a car or 2

Are you redoing the upper strut bushings. I have 2 sets sitting on the bench but they don't fit correctly. I asked about them 2 months ago but got no reply.

I have the same issues with my new bushings that I purchased at PP..
Gap at the top side lower is fine. I'm told it's because the housings are 914.
The 911 housings are different.
