About This Ultimate Pinewood Car Weights kit (Gravity + Friction)：Conquer the two biggest factors in racing with one kit. You get a complete 5oz hybrid pinewood weights to maximize potential energy (gravity), plus a large 0.5oz bottle of premium pinewood car graphite powder to minimize friction. It is the perfect "victory-in-a-box" solution for building a championship-ready pinewood car. Smart "Bulk + Fine Tuning" Strategy: Build a winner in simple steps. Step 1: Peel and stick the 12 rigid derby car weights to build your base mass (approx 4oz). Step 2: Use the moldable tungsten putty to tear off tiny pieces and bridge the final gap to hit exactly 5oz. Final Touch: Apply the included graphite powder to your pinewood car axles and wheels to minimize friction and maximize speed. High-Performance Graphite Lubricant:Includes a generous 0.5oz bottle of fine powdered graphite (3000-mesh) with a precision needle-tip applicator. This lubricant works in tandem with your pinewood car weights to ensure that every ounce of potential energy is converted into kinetic speed. The needle tip allows you to inject lubricant directly into the wheel bore for a silky-smooth, glass-like rotation. Simple, Tool-Free Operation Experience:The installation of all accessories—from the stick-on pinewood weights car kit to the graphite powder—is intuitive and straightforward. No complex tools or drilling are required. Novices can quickly position the peel-and-stick derby car weights and apply the lubricant to complete the entire performance upgrade in minutes, saving valuable race prep time. Safe and Reliable:This derby car weights kit (featuring non-toxic pinewood weights derby weights and child-safe graphite powder) is made of high-quality materials, ensuring the safety of children. Parents can rest assured that their children can safely handle these derby car weights and lubricants while participating in the production and excitement of the competition. Master The Physics Of Speed (COG): Winning isn't just about total weight; it's about placement. Stick the flat derby car weights low on the chassis for stability, then mold the high-density tungsten weights putty at the absolute rear to shift the Center of Gravity (COG) backward. This optimized setup maximizes potential energy while the powdered graphite minimizes drag.
