CHARLOTTE, N.C. (AP) — Ross Kenseth, son of NASCAR champion Matt Kenseth, will spend Father's Day weekend leaning on his dad as he prepares for his first Xfinity Series start. Kenseth will drive the No. 20 Toyota that his father, the 2003 NASCAR champion, often pilots in the Xfinity Series for JGR. "There was a lot of things beforehand that he told me about the way those cars are aero-wise, how hard it is back in traffic to get around guys, position yourself not to get yourself into a tight spot, which I think helped me out quite a bit," Ross Kenseth said. [...] come actual race time, Matt Kenseth was fairly quiet on the radio — a practice he picked up when his son first started racing. Knowing how to advise has been a learning process for Matt Kenseth, a two-time Daytona 500 winner. The renovation will have transformed the speedway with 101,500 new, wider seats, thousands of premium club seats, 40 escalators and 17 elevators, 60 luxury suites, social "neighborhoods" and three concourse levels that will span the nearly mile-long frontstretch.
