Abs can not prevent a spin once the car has exceeded a certain amount of slip angle. The car movement is lateral in a spin as supposed to the direction of tire rotation. Once a tire is going in a direction perpendicular to tire rotational axis it is not possible for any driving aids to help. About the only thing that may help would be lateral thrusters like a space ship. Apparently Porsche has heard about your Gt3 experience at Pocono and all the other tracks you have spun at and is considering implementing this as its future stability control system. Of course it will require a new fancy acronym. Its going to be called POSISAPS. which stands for Porsche Oh Shit I'M Spinning Again Prevention System. I look forward to driving one. It is also rumored they have recruited several RTR people to aid in its development. The information about the cars that hit the wall were based on the statements of the drivers and the continuous desire for abs to reestablish wheel rotation. This keeps the car form just locking up and going harmlessly down track. Instead the abs carried the car across the track into the wall. If the abs is sensing wheel rotation it will prevent lock up. If a driver turns in early and runs off at track out than locks up the wheels they will spin and the car will travel in the direction of travel. If this is going down track they will simply slide down track but due to the abs not allowing lock up unless the cars is completely sideways where no wheel rotation is present the abs will keep the car going in the direction of travel even if it is towards a wall. If the distance is less than the required distance to bring the car to a stop impact will occur as it has on several occasions. This is according to the people involved in the incidents. I do without question that ABS has certainly prevented more incidents and impacts than it has created but unfortunately the systems can only function according to the parameters set forth by the abs control system in the vehicle.
