Others may disagree but for me if the rubber looks good, feels good and is not deformed then just reuse it.

Are you planning to make mods that allow you to re-index the torsion bars on the car?

Elastomer bushings and shocks that have 100K and as many years as ours do are highly unlikely to be functioning to original design specs. They may look and feel OK to individual in situ inspection, but performance would likely be compromised.
That's not to say you can't use them, just that they aren't performing to original design specs. In reading owners impressions post bushing change, regardless of make, the perception invariably is positive and makes the vehicle feel 'newer'. I think it depends on what your priorities and budget dictate. Something else to consider is bushing material and technology have improved as well, so there would also be a benefit, even when compared to dead stock OEM that have been sitting on a shelf somewhere.

I’m keeping everything stock. But I have thought about getting adjustable spring plates to help with re-indexing.

To me it seems that the two upper carrier mounts are original and in bad shape. The rubber is galvanized. These are #4 and #5 on the PET chart. But of course they are not available anywhere it seems. I’ve seen this mentioned in other posts. Any ideas?

I was wrong. I was able to find both Porsche OEM torsion bar carrier bushings (for the upper spring plate and banana arm). Where they attach to the car it does seem that new rubber should improve the ride in the rear. They were not cheap so hopefully they do make a big difference.

Also decided to replace all the other bushings. If I’ve gone through all the trouble, I might as well and not regret it later.

Just waiting for everything to arrive.

Probably time to replace.

Thats one of the great things about cars, older suspension and isolation bushings can be replaced relatively inexpensively...human parts not so much.....one of the reasons we are mere care takers of our beloved machines as well maintained ones will likely outlast/outlive us.

Ready to start assembly.

Looking forward to trying the Prekom adjustable spring plates. Seems indexing the torsion bar won’t be as difficult as I will have plenty of room to adjust. At least that’s what I’m hoping for.

(Edit- seems the adjustability might be the same as stock, so will still have to pay attention to indexing. Will try to confirm.)

Haven’t seen many reviews on these. For the price and adjustability they seem like a no brainer. Comes with the bushings pre-installed, which to me is huge plus. Did not want to even think about the effort needed to remove the old ones. I’m getting lazy!

Getting closer though. I had an old basketball injury repaired last year, ACL and 2 torn meniscus on the same knee, that has given me a fresh start. A surgery that was unthinkably or possible 4 or so years ago. Feeling great

Your right though, someday they will be a generations Model T lol

Have you started the install, yet? I am planning some suspension bushing replacements and interested in the Prekom.
Thanks

All done actually. It wasn’t as bad I thought, though I did I got the torsion bar indexing wrong. Lowered the car about an inch and a half to much. But it gave me a reason to try out a coilover. But that’s another story.

The Prekom’s are great. Honestly can’t tell the difference between OEM. Really well made. Reading some horror stories about getting the old bushings out, I feel the Prekom’s with the bushings already installed are worth it. Though I will say the adjustability is the same as stock. Meaning you can’t go any higher or lower.

Overall the job wasn’t that difficult. Though I did have someone help me disassemble and final assembly. Along with new shocks, the rear now feels alive, that’s the best way I can describe it.
