Tillotson Racing presents the Tillotson T4 Series—a new category of racing that provides cost-effective entry into the sport of karting. The T4 Series is designed to increase participation in karting with a user-friendly kart package that provides an easy to learn and competitive experience for both new and seasoned drivers. The T4 Series is the new base of karting! The T4 Series runs a mono-brand Tillotson kart chassis developed to suit the Tillotson TPP-225RS engine and specifically-designed tyres. In order to control costs, only stock chassis and engine components can be used in the series, and there is a dedicated technical rule set for the kart, engine and carburetor. All countries will run the same equipment and rules package. Each year, the top drivers around the world will come together to compete in the Tillotson T4 Series World Finals.
