Welcome to Aztec Speedway - Your Hub for Everything Car Racing!

BOETTLER BOMBER RULES

These racing rules are designed to encourage a safe, competitive class while keeping a limit on spending. In no way will the rules be interpreted to allow a car that is technically superior to dominate the class or to be constructed in an unsafe fashion that poses a danger to the operator or other competitors. Any driver found outside the parameters or spirit of these rules will be sternly dealt with and faces fines, disqualifications, and possible disbarment. Interpretation of any or all of the rules is at the sole discretion of Aztec Speedway and its tech personnel. Let's keep it in the spirit of what these rules are designed for. Thank you in advance for your cooperation!
