The idea behind this division is to keep chassis and engines as stock as possible in order to hold expenses down. While the above rules offer a good outline, every item cannot be covered by a written rule. If you want to run anything not covered in the rules above, ask first! The officials and management reserve the right to adjust rules to make the class more competitive. Teams with different Home track rules may be accessed and penalized with a disadvantage to equal out competition as the division is developed. Be patient and have fun!
