Performance Chart of Outlaw Wheels vs. Standard BSA Wheels Benefits Easy to Use - These wheels are ready to roll. No preparation required!

Fast Starts - Very light weight for the fastest starts possible. Minimal Friction from Car Body - Pre-beveled hubs minimize contact with the axle head and car body. Minimal Track Surface Friction - Extremely small contact patch minimizes track friction. Minimal Lane Guide Friction - The wheel sides are beveled to minimize contact with the lane guide (see Figure 1). Well-balanced - Machined from Delrin for uniform density throughout. Computer Designed - To provide the maximum mechanical advantage over axle friction. Usage These wheels are ready to roll - just lube and go. Do not sand the tread surface as this may detract from performance. Make sure to mount the wheels with the "dish side" towards the car.
