I did the rears on my 1985 911. Nothing special. I took it to tire shop to break the lower bolts loose. I think I used Bilsteins, non-sport per recommendations.
I research the struts in front. This is a whole nother story.
After replacing rears at ~150K miles the Boge struts were still good. Stopping very flat.
I still have the research on the fronts. Send email to
