Re: Torsen differences

arrrggggghhhh,  the *part* numbers are *different*.  agreed?  the torsens
*look* different in the diagrams between the ur-q and the rs2.  could it
possibly mean that they *are* different.  just possibly? sheesh.

wooahh, you mean audi specially designed the 6-speed with too much room for the
[old] torsen?  you've got to be kidding.  surely.  why would they *possibly*
want to do this?

you agree that the helical spring isn't in the 5-speed?
