Usage:

The NPWDRL Street Stock Pinewood Derby® wheels can be used without any additional preparation, but for the best performance please follow these steps.

  • It is important to prepare the wheels for the proper lubrication. Each wheel bore should be polished resulting in a slippery smooth surface. As an example, do not use graphite to polish if you are going to use oil as your lubrication.
  • The hub (inside and out) along with the inner edge of the wheels should be polished to a slippery smooth finish
  • If you are not sure how to prepare a set of wheels consider having Derby Evolution prepare your wheels with the Revolution Race Prep Process
