Welcome to the web home of SPEED! If speed is your need, Dr Fast has your prescription! Dr Fast is quickly becoming a household name in the karting world. Although Rudy Wade and Mike DeHart have been making horsepower for decades, the "world" has just recently learned who "Dr Fast" is, thanks in part to our signature work aptly dubbed, Stealth Porting. We are also the newest distributor for DynoCams, which gives us the "edge" you need to win races! Cruise the site, enjoy yourself, and contact the Dr when you want to go FAST!!!
