I have done some research few days ago, and I have found out that we can make the car go faster by wearing the elastic band on the wheels. (only the back wheels maybe. And Kimi asked about this idea to Mr Ward and he had confirmed with the idea that the elastic band would increase the friction between the wheel and the track so the speed will as well increase. Here are some other keys to make a car go faster:
- Lighter car goes faster/ use the lightest material.
- Increase the friction between the rear wheels and track
- More mass over the back wheel, the less the rear wheels spin.
- Wheel goes faster without rubber.
- Use double sided tape to stick bearing under the chassis
- Lubrication / oil and grease
- Friction free for all the part touching
- Balance the wheels – sand down the wheels.
