I have done the pine wood for cub/boy scouts and mine were also inspired by Indy cars, but looked no where like yours. Last year my wife signed me up for the Awana grand Prix (I can't find any real difference except some of the rules). Since everyone knew I am a car guy and a model builder, the pressure was on. I have always had issues with the hieght of the bottom of the cars. While in the scouts, I had always added wood between the wheels, level with the bottom and not past the sides of the wheels. Last year, I took it to a new dimension with my side extensions. Not only did I go out, but I also took them down with in the width of the wheels so it did not rub anything. I am sure you can see my inspiration for this design. I did restrain myself and not paint it red. It is supposed to be a grey/green color changing paint, but will change about any color. I have seen blue, purple, gold and red. It pasted all the requirements (even with complaints) and was able to compete.
