Last year, my ESP Mustang had no ABS and it sometimes locked up in the
rear, sometimes in the front. This year, I put in the ABS from a 98 Mustang
Cobra and the ABS has independent adjustments for front right and left
wheels, with the 2 rear wheels on a third adjustment channel, so I get
dynamic brake biasing for free. I wonder if ABS systems and vehicle/course
dynamics are so varied that it is nearly impossible to say much useful
about ABS generically ... that specific vehicle, driver, and course testing
is necessary.
