We should be able to run BB al the way to 58 59 ish without spinning out. Like ACC but I like AMS 2 better
If you don't brake too hard, you won't spin out. The BB depends on the type of car and your driving style. If you set it forward you will be able to trail brake deep into the corner. If you set it more to the rear the car will turn in easier, but slow down less. The numbers of the BB don't say much and is different for every car and track combo. It has to be the feeling of the car that decides where you have you BB.
