Alas, nothing for the rear off K-mac. There's a place in the states you can get a rear camber arm for the Stanza. Last I checked it was ~$250 inc post.
The front strut tops specify, "R31, Skyline, Pintara" - normally I'd assume this means the R31 pintara only, but it states it's for years "86-97". That's a helluva lot longer than the R31s were in production. Skyline or Pintara... Fling them an email to make sure. I'm not picking up a set yet because I can't justify $500 on camber tops just yet, so I haven't looked into it in any more detail.
Either way;
