all front wheel drive do that, thats physics, the back of a rear wheel drive will get up.

thats the power applied by the front wheel, it force the body of the car down when going forward, thats why going reverse we got plenty of traction, ...part of the weight transfert.

I don't remember the pre-2000 models doing it like the 2000+ models do. You can distinctly feel the rear end drop low..

Set parking brake and watch it when you move. Same effect.

The 2000 and newer will be worse than the 92-99. Simply because of the higher CG and weight transfer problems.
