I’m rebuilding the rear suspension on my spec project at the moment. I am ready to order all the rear bushings and wanted to get some info from you guys on the ajustable bushings versus the regular ones. How many degrees of adjustment do you gain with them? Are they worth the extra money?
Thanks,
The problem with adjustable bushings is that it is difficult to align the rear wheels, and as Craig says they may not retain their adjustments over time. If the trailing arms and subframe aren’t bent, plain bushings are good enough.
I hope you are also replacing the subframe bushings and diff mount…
We have adjustable on one car, and fixed on another. To be honest, the regular, non-adjustable RTABS seem to be working better. We don’t get much adjustment from the others. You can search the forum, there are some previous discussions on this issue. As noted earlier, the subframe and trailing arms need to be straight.

Hey - I guess you get to talk to me vs. the wife on this (we have different thoughts on the rear suspension parts).
I was having a discussion with one of the RRT guys - his thoughts were to get the OEM Rubber offset ones (very little known parts - they are in the parts catalog - if you need part numbers, I can look them up). His concept was the compliance in those bushings were a good thing - I will try to find the thread on Bimmerforums. We currently have the KMac offset urethane ones installed - they seem to not suffer from the adjustment issues other seem to have with the same part. But - if I were to do it again, I would probably go rubber, or with AKG all the way back (engine, tranny, diff and rear arms). I like keeping all the material the same on the first 3 parts, as they all move (to some degree) together. Better put - don’t’ have 12 year old rubber engine mounts and delrin tranny and diff mounts.
I went w/ AKG all the way around. Still fighting with the subframe.(D/S bushing is melted to the stud)
