1 G - Derby Worx Pro Ultra- Lite Speed Wheels are precision machined on a CNC lathe. The  OD of the wheel is lightly machined. This makes the OD of  the wheel concentric to the wheel bore and removes the mold mark on the wheel for a perfectly flat and concentric wheel. The inside of the wheel is machined to remove material thus creating the ultra light wheel  without modifying the outward appearance of the wheel..  Lighter wheels have less rotational mass and turn much easier than standard BSA wheels. Lighter wheels also allow you to put more weight to rear of car which which gives your car more potential energy to release as the car rolls down the track. Wheels are matched by mold number for a perfectly matched and balanced set of wheels. The wheel hubs are coned to reduce friction when wheel hub rubs against the car. All material is removed from inside the wheel and the wheels are

Stock Appearing from the outside.  These wheels weigh 1 Gram, compared to stock BSA wheels of 4 Grams.  This allows the usage of 12 more grams of tungsten in the rear of the car where there is the most kinetic energy.
