"what bushings?"
It's the bushings in the front control arms. The rubber gets sloppy so replacing them with a kit from Powerflex is a good idea (there are other brands to, I think a guy here on Rennlist sells a kit). They make a difference and still works for street use. Bushings made of delrin or steel/solid as the RSR is no use for your set up.

I was considering having refurbished front lower arms at the time i was having the suspension done. However due to the supplier missing his delivery date I went down the Powerflex road! The old bushes were a b*tch to remove (two per wishbone), but well worth the effort. The Powerflex just press in, which will make replacement in the future a doddle. Well impressed with the Powerflex bushes.

The bump stop (#8) is not required on the Bilstein rear shocks, as they have an internal bump stop - I THINK. It is either front or rear, and my memory is not 100% sure any more. I recall contacting Bilstein tech support, and they confirmed which shock does not require the external bump stop.
(you might find that if the bump stop is used, then with the lowered stance the shock may ride very close to the bump stop and thus significantly change your spring rates. I have a really good article on the contribution of bump stops to the overall spring rates - by design. It is written for 996 suspensions, but the principles are the same. If I can figure out how to upload the article, which is a series of fairly large pdf files - anyone help me post these?)

These are the people that I contacted 2-3 years ago. I asked for technical assistance with part numbers X. They also rebuild and revalve shocks at the location.

I'm having problems contacting Bilstein over the phone with the time difference - is there someone that can call from the US and ask if the bump stops are needed (see earlier in this thread) please? I need an answer soon as I want to fit the HDs before spring comes and don't want to get it wrong.

The rear struts have internal bump stops, front don't. Had my HDs and H&R Greens fiited two years ago and remember that most clearly; along with the non-inclusion of the rear sleeves.

I got nothing back from Bilstein.
Gert from Carnewal confirmed the following to me though:
The fronts have the bump stops built in.
The rears come with new ones IIRC.
I am now looking for a trustworthly specialist to install them for me at a reasonable rate. I tried Gert, but he said he wouldn't install them, because I didn't buy them from him... so my search continues. I had a really good offer from my local tyre dealer and the guy that would install it is a Porsche enthusiast (owned 3.2s in the past) - but should I trust them?
Whilst looking around I had a comment from JZM (in the UK) that I compromised by buying the Bilstein HDs and H&R spring combo (because they are the cheap option) and that I should have gone for the KW V3 system. I would be interested to know how many of you 964T owners regret putting the Bilstein HDs on your car?

I replaced mine at 46,000 miles because the ride was harsh. The shocks felt tight except for a slight looseness at the start of the stroke. That little bit causes the harshness that is the first symptom of the shocks going bad. The ride is still fabulous six years and 30,000 miles later.
It is not a bad DIY if you can get the springs compressed safely, get the lower bolts out of the rear shocks, and have arms long enough to reach the top bolts on the rear shocks.
