As I start watching more and more autocross I start to notice all the attention played to abnormally huge down force adders. So I made a little picture that includes the two main type I see at the events and my question is …WHICH ONE IS BETTER?? It seems that they would both have their pros and cons. But which is the better of them? If you run a rear spoiler or wing why do you run that one over the other?? Type a vs. type b?
