[V8] V8 rear calipers shared?

[Ingo Rautenberg]

I see now.  The 447 615 423 and ... 424 applied to the other (lesser)  
100/200 Audis with, according to ATP "higher permissible weight  
option."  Probably available everywhere but the U.S.

I imagine you could use the lesser ones --  but in any case the pair  
should have the same piston size -- and obviously the later, more  
powerful cars had the larger pistons.
