RS Racers are the most scientifically advanced Pinewood Car Derby racing wheels on the Planet Earth. These are NOT official BSA® wheels. They have been precision cut from a solid piece of Delrin using a CNC lathe. Intended for open class racing, they are simply put, the fastest wheels available anywhere!!!

Speed features:

- A Patent-Pending Anti-Friction wheel surface design, which reduces contact with the track guide strip to just 0.002 inches. a killer speed advantage!

- Wafer thin design reduces wheel to track surface friction.

- Each wheel weighs in at just 0.7 grams each. Standard BSA® wheels weigh a full 3.5 grams. Lighter wheels begin turning faster and take less energy to make them spin. Result: These wheels are like nothing you have ever seen before!!

- CNC milled to be perfectly smooth and round.

- Wheel hubs are tapered and polished, reducing hub friction to a minimum.

- Wheel tread surface is polished and perfectly smooth.

So, if you want the absolute best wheels available in the entire world, look no further. RS Racing Wheels are the BEST THERE ARE!!!
