Lower downforce expected for XFINITY cars: 2017 brings a significant change to the NXS racecars: a decrease in downforce. A source says that NASCAR is shortening the spoiler by three inches and making it narrower by four inches. The sport is also mandating teams make the cars’ front splitters an inch lower and change two other dimensions on the lower front nose of the car. This should decrease speeds and handling and make for more passing. But these changes could also be harder for smaller teams to adapt to, since bigger teams have budgets to better implement them.(WSB Radio)(1-13-2017)
