How does friction affect the speed of a co2 car?
Friction acts on all cars the same pretty much, model, rocket or tank. I am assuming this is a model race car though.The three important factors to look at are air resistanceRolling resistance (wheel to track and wheel to axle) I used to use no residue and no smell silicone dry sprayBody to track. How will the body of your car react if it touches the side of the track and can you use a Teflon coating? If not use the dry silicone spray and hope no one notices (it is cheating in most cases)
Remember the old Nascar saying "If you ain't cheating, You ain't winning"
