Diff plugs (Jay Kempf)

[Tony Hoffman]

Early type 44 chassis Audi's with manual transmissions had open centers
with lockers, as well as rears. No torsen till the 100/200 line. Then the
V8. All V8's in the 'states have 4.11:1 final drive ratios. All have torsen
rear differentials. Manual trans ones also have center torsens, auto's have
open centers with electronic locking.

When speaking of "Auto tranny Quatros", I"m assuming you mean the V8's
specifically. Many of the later auto trans Quattros have a torsen center
differential.

Which is better is a matter of opinion, some people prefer the Torsens,
some prefer the lockers.
