At Over-Under Racing, we take pride in having brand ambassadors who exemplify the spirit of sportsmanship and positivity on and off the track. These racers are not only skilled competitors but also supportive mentors who foster a welcoming environment for newcomers and seasoned drivers alike. Their dedication to fair play, encouragement of fellow racers, and passion for the sport make them outstanding representatives of our brand. Through their actions and attitudes, our ambassadors help build a community that values respect, teamwork, and the thrill of racing. We support those who support others and our sport.

He is not only a great driver and coach, he also is very immersed into the mechanical side as well. Chuck performs all of his own work on his karts and engines. He is extremely well rounded in the sport and was the perfect person for Over-Under Racing to partner with to grow the 4-Stroke program.
