Dave, it helps to think of squat as the car's suspension actually trying to pick the rear tires up off the ground rather than as the result of weight transfer. In most situations in most RWD cars, squat is caused by both. But the result is always the same: squat actually unloads the rear tires as it happens, rather than loads them. Once the suspension reaches "full squat" (static), then the full tire loading from the weight transfer occurs - but until the suspension stops moving. In any car with less than 100% anti-squat (almost all of them), you can set the parking brake and try to accelerate and the rear will still squat, even if the car doesn't roll. That's the suspension trying pull the tires up into the wheel wells, and it hurts drive traction. In cars with more than 100% anti-squat, the back end will lift up instead. That's what drag racers really want. You'll never see a serious drag racing car squat on launch - you mostly notice the front end rise.
