Couldn't find it in a previous thread so...
Does a driver's weight have an effect on their star and driver level?
Weight is currently turned off until a future update introduces BMI. However, it is a mistake not to train your drivers down to minimum weight. If you don’t when it is switched back on again it will impact your speed (especially in qualifying) and it becomes more difficult to reduce weight the higher the level your driver becomes. This is why standard strategy is to max Staminja and get weight down to minimum before doing any other type of training.
