[V8] V8 rear calipers shared?

[QSHIPQ at aol.com]

Yessir, ETKA and ATP doesn't help here, the vented  rears have also been 
listed for years as on 5000tq  wagons and 200tq wagons <ALL>, even in the USA 
cars.  Never seen  it except on the 91 200w, and it uses a unique rotor (also part 
of  the 5ktq/200 wagon app).  Ingo, I'm pretty sure you *can't* use the  
smaller caliper on a v8 (hence my not interchangeable), IIRC the 36/38 caliper  
claw won't be wide enough to stuff 2 brake pads and the vented rotor with the  
piston fully retracted.  You *can* put the v8 rear caliper (with  carrier) on a 
early 5ktq/w using the 91 200 rear rotor...

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.
