I have a question about wheels and axles. I have been building pinewood cars with my son for 3 years now. We have always followed the rules of what is allowed. However, no matter how fast my sons car is it is always 4-5 one hundredths of a second slower than the fastest cars in our pack. This year his car was even faster than last years council winner. I have noticed that while we play by the rules others are not. I have tried doing things the right way and don't like seeing my son so dejected when it doesn't finish well. What type of wheels would y'all recommend to make his car more competitive. He wants to go to council derby this year and his car is running a 2.60 on a 30 foot track at 189 mph. The fastest cars are running 2.55 to 2.56.
