Just a note: The H3 has dynamic rear proportioning via the circuitry of the EBTCM and the lines to the front and rear brake calipers. If marketing says it will prevent the front end from diving, they are incorrect, and should be hung at dawn. Even, with NO front brakes, a sudden apply of the brakes will cause the front end of any vehicle to nosedive...something about physics.
The dynamic proportioning circuitry primarily takes effect during extremely heavy braking; a lot heavier than I hear here about the groaning noise. A lot heavier than my groaning noise that went away with a new t/case.
