CBR Cars
Over the years, the boys have progressed
through various classes. Starting out in a youth hornet, both boys then
moved to the IMCA Hobby Stock and then to the IMCA Northern SportMod.
In 2014, the boys once again raced each other in the SportMod Division.
This hasn't happened since they were racing Jr. Kage Karts. In 2015,
they began buidling their own Homemade Chassis.
