So, i keep seeing people talking about it and finally i decided to find out what it is and why it is so important. Now, i understand what it is and partly what causes that but i don't understand how that information can be usefull. To be more precise, once i know the slip angle, the slip ratio and everything, what should i do to improve the performance of the car based on those information? I searched for a while now and i found many sites that explain what it is, but none that explain how to exploit that information in order to "make your car faster". P.s. I was interested in buying some URD packs, but i don't know which of those are the most used online or for leagues, any suggestion?
