locking diffs? was: Boating with an S4

[Anand Dhanda <dhandas@cwixmail.com>]

but one thing that is quite noticable is that this "traction-hookup" is not
created super quick, in our bone stock 98' A4 2.8Q if the ground is wet and
you do a "racey" launch the front tires spin for a short while then it moves
power to the rear which throws you back in your seat.
