When the heavens open and the track is awash it fundamentally changes your car’s interaction with the track.
Your relative grip compared to your power output drops significantly so you will need to get the car turned further and pointing more at the exit before you go to the power. Your inputs need to be more measured and smoother to avoid overstepping the lower grip limits but most importantly your vision will move in closer to the car.
Closer vision allows for better reading of the expected grip levels on the road surface ahead. Look more in the mid-range than far away so you can pick up puddles and high grip areas and aim your car accordingly.
