Porsche GT3 Brake Bias Tip
Found an indicator that you need to adjust the brake bias. If the lights turn purple on dash it’s an indication that you are locking the front tires, orange for the back tire lockup. If you’re seeing purple lights on both sides it means you need to move your brake bias rearward (so needs to be moved negative). Opposite for rear tires lockup, but that is less likely to happen with the default setup.
The basic advice for brake bias is to move it as far back as possible before oversteering and spinning out. This dashboard light thing is something I just figured out. I got the info from the iRacing manual for the Porsche.

WHEN TO SHIFT
The manual also states that when the shift lights turn blue is the best time to shift, so not when it just fills up.
