I posted a comment a while back about wheels and axles and got some great info. I stated that my son always finishes around eighth in his pack every year. He finished eighth in his pack this year so I decided to do something different for council derby. He was 4 one hundredths slower than the fastest car at our pack derby. After reading our rules I ordered a set of speed axles and nitro wheels from derby dad. These allowed us to stay within our council rules. I just wanted to say thank you to derby dad 4 hire. He went from eighth in his pack to first at council. That's right eighth at pack pinewood derby to council champ. I want to say a sincere thank you to you for the great wheels and axles. They did the trick
