though i have never tested it on an adjustable height 2WD car, high diff's lock up the rear of the car on power, lower diffs make it free'er on power
one of the reasons the xxx4 was so bad on the bumps was because of the huge diff's leaving the outdrives really high, compare that with the diff on the xx4 and how good that was (is) on the bumps.
I think on 2WD the diff height (with regard to 'grip' ) higher makes it square up more on corner exit (on power) and lower makes it softer so more roll and general 'grip' ?
- I'm not entirely sure on this as ive never tried and adjustable diff height 2WD car
EDIT - having said all that, theories are great, but actual testing of something attached to a specific car with all its other geometries working together is what really counts so the effect of diff height in the cougar could be slightly different to that in the X6.
