3.25 oz Tungsten Pinewood Car Weights + 20 Page Step-by-Step Build Guide for Apollo 2000 Derby Car Showing Design + Weight Placement, Bring Your Car to The 5 oz Limit and Gain The Winning Edge

Key features

• WIN BY 3+ CAR LENGTHS: It's science. When these weights are place toward the rear of your car, you will have more potential energy because your center of mass is higher up on the track which will result in maximized kinetic energy at the finish line.
• STEP-BY-STEP BUILD GUIDE BOOKLET FOR APOLLO 2000 PINE CAR: Our build guide (now a physical booklet included with your order) will show you how to build the Apollo 2000 derby car. With 20 pages of detailed instructions and illustrations, this guide will cover body design as well as exact tungsten weight placement to achieve a 4.8 oz derby car with an ideal center-of-gravity for maximum speed. The final 0.2 ounces are added on race day using the official scale.
• MORE WEIGHT FOR YOUR MONEY: 3.25 oz instead of 3 oz! This means you can locate even more weight to the rear of your derby car for maximum speed.
• HIGH DENSITY & NON-TOXIC: Our tungsten is of 99.95% purity and is 1.7X denser than lead, meaning that it can add significant weight while maintaining a small footprint. Being non-toxic makes our weights safe to handle as opposed to lead.
• EASY INSTALLATION: Simply drill a 3/8 inch hole using a standard electric drill (Forstner bit HIGHLY recommended), insert your weights and glue in place.
