Well, one can reduce rear grip with adding gas even further to level of complete overcoming traction, and go sideways drifting. Skidding tires will certainly have less traction then still having grip fronts. But, it's not norm to drift through every turn on public roads, and drifting is slow way to go around track.
Are you sure that it's increased mass transfer that increases grip? Then how does a larger swaybar work?



The reality is there are more than one possible outcome from applying throttle in a corner with a rwd car.

First is - more speed - more cornering force required from the front - front tires are already at a high slip angle - more understeer results

The other possibility - more rear slip angle due to both acceleration force and additional rear lateral weight transfer - reduced understeer

Third option - wheelspin - much more rear slip angle - reduced understeer. Maybe hard to do in a stock power brz especially with good tires.

However, the first two are both possibilities. Kind of depends on power and how well balanced the car is at steady state. We've setup cars to be fairly biased toward understeer to give the rear tires more ability to accelerate the car out of a corner.
