[Es2] custom RS2 caliper brackets: feeler post

This probably needs some elaboration.
First there are early(A8E?) and late A8 disks. I am guessing that A8L
stands for late because it is not any official Audi designation I
know. As for calipers there are also RS2 standard (RS2S) and RS2
optional (RS2O) if we stick with the convention. These are different
from the 996/BoxterS calipers.
My setup is A8E+RS2 brackets+RS2S calipers. These need washers. I have
a german reference somewhere with pics.
I have no direct experience with the 996 caliper + A8L disk + RS2
bracket. I have heard it is a straight bolt on.
I see now that I should have kept my mouth shut. This is kind of a
bucket of worms. Maybe the best thing is probably to just replicate
the RS2 bracket in the spirit of keeping one factor constant. The
alternative is to start making custom brackets for every concievable
disk/caliper combination which may be the road to madness.
