PineDash Pro Pinewood Derby Weight Bundle (12pc Silver + 3oz Flexible Strip) - Dual Power

Master Weight Distribution. Achieve the Perfect 5oz. Win.

Winning Pinewood Derby races requires two critical factors: reaching the 5oz weight limit and positioning that weight exactly where physics demands it. PineDash Pro Hybrid Weight System delivers both precision tungsten weights and flexible weight strips in one complete kit—the ultimate solution for builders who refuse to compromise.

The advantage is clear: This kit provides 7 total ounces of weight capacity (4oz tungsten + 3oz flexible), giving you more options than any competitor. Mix and match weight types to hit exactly 5.00oz while optimizing weight placement for your specific car design. Flexibility wins races.

Why PineDash Pro Hybrid Weight System Dominates

Dual Weight System Versatility: Combines 12 precision tungsten weights (4×½oz + 8×¼oz) with a 3oz flexible weight strip. Tungsten fits tight spaces and provides maximum density. Flexible strip conforms to complex contours and fills gaps standard weights can't reach. Together, they give you placement options competitors using single-type weights simply cannot match.

Scissors-Cut Flexible Strip for Perfect Weight: The 3oz flexible weight strip cuts with ordinary scissors to any shape or size. Need to add exactly 0.37oz to hit 5.00? Cut it. Need to fill the narrow cavity behind your rear axle? Cut it. This precision control eliminates the "close enough" compromises that cost you hundredths of a second.

Superior Tungsten Density Advantage: The 12 tungsten weights provide 4oz of high-density mass (1.7x denser than lead, 2.5x denser than steel). Small physical footprint means you can position critical mass low and toward the rear—the proven weight distribution formula—without interference from bulky weights.

Professional-Grade Adhesive System: Both weight types feature strong 3M adhesive backing that won't fail during racing. The tungsten pieces have wide paper backing for easy peeling and repositioning during testing. The flexible strip bonds securely to wood, maintaining position through dozens of heats.

Complete Kit Includes

• 12 Precision Tungsten Weights: 4 pieces × ½ oz + 8 pieces × ¼ oz = 4 oz total capacity
• 3 oz Flexible Weight Strip: Scissors-cut to any shape, conforms to complex surfaces
• Total Weight Capacity: 7 oz (enough for multiple cars or maximum flexibility)
• Professional Adhesive: 3M-grade backing on all weights
• Installation Instructions: Printed guidelines on packaging

Perfect For

• Complex Car Designs: Aerodynamic shapes, hollowed bodies, multi-cavity designs
• Precision Weight Tuning: Hit exactly 5.00oz, not 4.95oz or "close enough"
• Standard and Custom Builds: Works with BSA kits, custom wood blocks, 3D printed bodies
• First-Time and Veteran Racers: Flexible system adapts to any skill level

How to Use (General Guidelines)

1. Weigh Your Car: Determine current weight with wheels and axles installed
2. Calculate Weight Needed: Subtract from 5oz limit (or your race's maximum)
3. Choose Weight Combination: Use tungsten for primary mass, flexible strip for fine-tuning
4. Plan Placement Strategy: Position 70-80% of weight behind center line, as low as possible
5. Test Configuration: Temporarily place weights, roll car on test track
6. Cut Flexible Strip: Use scissors to cut exact amount needed
7. Permanent Installation: Affix all weights once optimal configuration is found
8. Final Weigh-In: Verify total weight meets race requirements

Pro Tip from Championship Teams: Use tungsten weights for your primary rear mass placement, then use flexible strip to "fill in" irregular spaces and achieve exact 5oz target. The flexible strip excels in cavities behind rear wheels or along the bottom edge where tungsten pieces won't fit. Some advanced builders paint the flexible strip to match car color for a cleaner appearance.

Flexible Weight vs Traditional Weight: When to Use Each

Situation	Use Tungsten Weights	Use Flexible Strip
Primary rear mass placement	✓ Optimal (high density, small footprint)	Alternative if space is wide/shallow
Filling irregular cavities	Difficult (rigid shape)	✓ Excellent (conforms to contours)
Fine-tuning to exact weight	Limited (fixed ¼oz increments)	✓ Perfect (cut to any weight)
Tight spaces (low profile needed)	✓ Best choice (maximum density)	Alternative if you cut thin strips
Wide, shallow areas	Requires multiple pieces	✓ Ideal (covers area efficiently)

Strategy: Use both types together. Tungsten for concentrated mass placement, flexible for precise tuning and filling gaps.

PineDash Pro Quality Guarantee

Every tungsten weight is manufactured to strict tolerances to ensure accurate weight specifications. The flexible strip is tested for consistent density and clean cutting. If this kit doesn't help you achieve the 5oz limit with optimal weight distribution, or if any adhesive fails during racing, contact us within 30 days for a full refund—no questions asked.

We engineer complete solutions. No compromises. No excuses.

Important Race Compliance Note

Always verify your local race rules before purchasing. Most Pinewood Derby competitions use a 5oz maximum weight limit and allow both tungsten and flexible weights. Some races may have material restrictions—confirm tungsten and composite materials are permitted. Weight capacity in this kit (7oz total) exceeds race limits to give you maximum flexibility in weight distribution.

Frequently Asked Questions

Why would I need both tungsten and flexible weights?

Different weight types excel in different situations. Tungsten provides maximum density for tight spaces and concentrated mass placement. Flexible strip conforms to irregular shapes and allows precise weight tuning. Using both together gives you more placement options than single-type weight systems, resulting in better weight distribution.

How do I cut the flexible weight strip accurately?

Use ordinary household scissors. To cut a specific weight: weigh your car, calculate weight needed, use a kitchen scale to weigh pieces as you cut. The strip cuts cleanly without special tools. Advanced tip: Cut small test pieces first, weigh them, then calculate length needed for target weight.

Can I paint over the flexible weight strip?

Yes. Many racers paint the flexible strip to match their car color for a cleaner appearance. Use acrylic hobby paint or spray paint. Let paint dry completely before final installation. Painting does not affect adhesive strength or weight performance.

Will 7oz of weight be too much for a 5oz race?

The 7oz total capacity gives you flexibility—you don't use all of it. Typically, you'll use 4-4.5oz to reach the 5oz limit (accounting for ~1oz car body/wheels). The extra capacity means you can test different weight combinations and configurations without running short. Save leftover weights for future cars.

Which weight type should I use first when building?

Start with tungsten weights for your primary rear mass placement. These provide maximum density and are easier to reposition during testing. Once you've established your base weight distribution, use flexible strip to fine-tune to exactly 5.00oz and fill any remaining cavities. This staged approach optimizes both placement and final weight.

Safety Information

• Tungsten weights are non-toxic, unlike lead alternatives
• Flexible strip is non-toxic composite material
• Adult supervision recommended for children under 8 during installation
• Small weight pieces—choking hazard for children under 3 years old
• Use scissors carefully when cutting flexible strip
• Adhesive is permanent once cured—plan placement before final installation
• Wash hands after handling weights

The Complete Weight Solution

Most weight kits force compromises. Single-type systems can't adapt to every car design. Tungsten-only kits leave you short when you need to fill wide, shallow spaces. Flexible-only systems lack the density for optimal rear-weight placement.

PineDash Pro Hybrid Weight System eliminates these compromises. Precision tungsten for concentrated mass. Flexible strip for exact tuning and gap-filling. Together, they deliver weight distribution flexibility that single-type systems cannot match.

Champions don't compromise on weight distribution. Neither should you.
