There is no mention of this in the '87-'88 manuals, but
'89-up sedan manuals state that Teves ABS equipped cars
have a Torsen diff (TORque SENsing). This type of
limited slip diff is supposed to be much better than
the normal clutch-type because it is activated by torque
as opposed to axle-shaft speed. Supposidly, it can
limit slip BEFORE a tire begins to spin.
