What Drivers Say About Us
Brad Majman
SKUSA SuperNats, AKC Round Winner, USF2000 Driver

"Kart Class has been a great resource to use when I’ve arrived at tracks that I’m new to and need to pick up within the first session. Using the track guides from Kart Class and the expertise that Dave provides, picking up tracks quickly is now one of my strengths. This all comes from the trust and confidence that I have in Dave, both as a driver coach but also helping me on the kart setup side of things."

William Calleja

"The Kart Class Champions Program has been fantastic for me, because I have been able to gain tips from Dave about driving styles, how to deal with setbacks, and special techniques like braking in the wet. It’s just like having Dave with me at the track on demand. The technology is great and I can replay the videos as I need it. I recommend the program for drivers who want to learn from a champion like Dave Sera."
