**While the above rules offer a good outline, not everything can be covered by a written rule. If a car has a part that no one else has, and its not mentioned in rules, its not assumed legal. Ask first. If you want to run anything not covered ask Jim Mazur at 585-344-1656 or 585-472-1031 first before doing so. If you don’t ask and anything is found it will automatically be ruled illegal. Any item found illegal will be confiscated!
