I'm glad you brought this up Growling as I'm just about to purchase a few bits for the rear as well.
I'm on Bilstein B6/Tein S spings and was going to get the rear adjustable camber arms with lockout bolts.
But now it sounds like there won't be much choice to adjust the toe, hmm.
EDIT:
Ok, I just did some more reading (always helps), and now have realised the toe adjustment is from the oval washer on the spring bucket arm.
So an adjustable camber arm + lock out washers should be fine, and will just have to hope for now there is enough adjustment on the bolts (I do have the eibach bolts in a box somewhere).
