3.25 OZ Cylindrical Tungsten Weight for Derby Pine Race Wood Car
These weights come in a total of 14 pieces with multiple small increments (1/16 oz to 1/2 oz). The set is crafted from high-purity tungsten (99.95%), delivering a density advantage about 1.7 times that of lead. The cylindrical design minimizes sharp edges, supporting safe handling for youth builders. The mix enables precise rear weighting to boost potential energy as the car travels toward the finish line.
Tungsten Weights 3.25 Ounce Cylinders
This set offers four sizes of cylinders: 1/2 oz, 1/4 oz, 1/8 oz, and 1/16 oz, totaling 3.25 oz in 12 pieces. Each weight is 3/8 inch in diameter, designed for precise placement and easy stacking. Tungsten’s density improves energy storage, supporting faster speeds with careful rearward placement near the axle. The kit emphasizes accuracy and repeatable tuning for consistent race-day performance.
30pcs Car Weights for Pinewood Derby
This kit provides a total of 5.25 oz of tungsten in four sizes: 1/2 oz, 1/4 oz, 1/8 oz, and 1/16 oz. The 30-piece assortment supports comprehensive weight tuning and replacement options. Tungsten’s high density enables heavier weights in smaller footprints, helping to optimize the car’s center of gravity and acceleration. The set is positioned for racers seeking flexible, durable components for frequent use.
QoTang 24 PCS Cylindrical Stainless Steel Weight
This 6.8-ounce set uses a combination of iron and stainless steel for durability, with four sizes ranging from 1 ounce to 1/16 ounce. The smooth cylinders have rounded edges for safe handling and installation. The kit emphasizes precise tuning for weight distribution, enabling builders to maximize energy buildup and achieve faster track times by optimizing the car’s center of gravity and back-end mass concentration.
Pinewood Tungsten Weights Kit
This Derby car kit includes 16 tungsten weights totaling 3.75 oz, plus two 0.5-ounce tungsten putty weights and 40 ml graphite lubricant powder. The weights are distributed as four 1/2 oz, four 1/4 oz, four 1/8 oz, and four 1/16 oz. The putty adds flexibility for shaping the weight distribution, and the graphite powder aids lubrication for smoother axle performance. High-density tungsten supports fast acceleration while maintaining a compact weight footprint.
Buying Guide
Key purchase considerations for tungsten weights include density, total weight, size variety, and ease of use. Higher density allows more weight in a smaller space, enabling optimized center of gravity near the rear axle for acceleration gains. Look for sets with multiple increment sizes to fine-tune balance and weight distribution without drilling or extensive modification. Consider the number of pieces and total weight to ensure you have enough replacements across multiple seasons or cars. Safety is important; choose smooth-edged cylinders and non-toxic materials for younger builders. Finally, verify that the product includes accessories like putty or lubricant if you plan a full tuning kit.
Performance considerations from multiple perspectives:
- Component quality: High-purity tungsten yields consistent weights and reliable performance across sessions.
- Weight distribution strategy: More weight toward the rear axle can boost acceleration but may affect stability; balance is essential.
- Practical handling: Cylindrical shapes with rounded edges reduce corner risk during assembly and testing.
- Maintenance and replacement: Sets with spare pieces reduce downtime between races or during car adjustments.
- Compatibility: Ensure the weights’ diameter and diameter are compatible with your car body design and any pre-drilled slots.
