51FIFTY Energy Drink Jr. Late Model Series 2017


This is an eight race SERIES in 2017 and it is televised on MAVTV! "The concept for the Jr. Late Model Series is something I've thought about since 2009, as I believe a restricted late model is a great place for a youngster to hone their skills in a car they can move up with throughout their teenage years. We are proud that we have built a series where talent can shine in the RPM Pro Late Model Series, and we intend to do the same for the 10-16 year old crowd with the Jr. Late Model Series on MAVTV" Kenny Shepherd.
