imo this is a bad idea to try to mingle with bias and TC during the race, as we don't have changing conditions (in that case that would be useful), maybe a click of TC can help with worn tyres or if you are willing to take more risks for a flying hotlap in quali, sometimes also just for the standing start. Bias although is important to get right, finding a good compromise between the best stopping power for all corners, at the same time for inline and trailbraking, it's your intitial impulse to catch the apex line (i guess what you refer as the yaw), very linked to aero as well, put more wing you can have more agressive bias etc.. but before it becomes a little dangerous, this is usually the easiest way to gain in laptimes through setup, so applies to fixed setup races as well.
