What You're Building and Why It Matters
A custom LEGO Speed Champions Dodge Charger police car combines the official Speed Champions Dodge Charger set with modifications, aftermarket pieces, and design choices that turn a standard build into something specific to your vision. The base set (typically the 76890 Dodge Charger R/T or similar variants) gives you a licensed, minifigure-scale vehicle, but customization lets you add police livery, change colors, swap wheels, or alter the body to match a real patrol car or a fictional design.
This matters because the standard Speed Champions sets come in civilian colors and configurations. If you want a police version—with light bars, decals, different paint schemes, or authentic department markings—you need to source parts separately, modify existing pieces, or commission someone who builds custom LEGO vehicles. Understanding what's available in the base set versus what you'll need to source elsewhere determines your budget, timeline, and the final result.
Key Takeaways
- The official LEGO Speed Champions Dodge Charger set does not come in police livery, so you must add decals, repaint pieces, or swap parts to create a police version.
- Custom builders source additional pieces from BrickLink, Brickarms, or other third-party vendors, or they modify existing LEGO elements with paint or stickers.
- A police-themed build typically requires a light bar (custom-made or sourced), police decals or stickers, and often a repaint or color swap of the body panels.
- Building time ranges from a few hours for decal-only modifications to several weeks if you're commissioning a professional custom builder or painting pieces yourself.
- Cost varies widely: a basic decal modification might add $10–30, while a fully custom-painted and detailed police car from a builder can cost $150–500 or more.
The Official Speed Champions Dodge Charger Base Set
LEGO's Speed Champions Dodge Charger (set 76890, released in 2020) comes in bright red or black, depending on the variant. The set includes approximately 247 pieces, one minifigure, and builds to a scale of roughly 1:64—smaller than a standard LEGO car but larger than a toy car. The body is sturdy, the wheels are functional, and the overall design is recognizable as a Charger.
The set does not include police-specific elements: no light bar, no police decals, no blue or white paint scheme. If you want a police car, you start with this base and add or modify from there. Some builders keep the red or black and add police markings; others repaint the entire body to white or blue first. The minifigure that comes with the set is a generic driver, not a police officer, so you may want to source a police minifigure separately if that detail matters to your build.
Where to Source Custom Parts and Decals
BrickLink is the largest marketplace for LEGO parts, both official and used. You can search for specific colors, molds, and elements—for example, white or blue body panels, transparent red or blue pieces for lights, or specialty wheels. Prices vary by part condition and rarity; a single custom-colored panel might cost $2–8. Shipping can add significantly if you're ordering from multiple sellers.
Decal and sticker sources include Etsy sellers who specialize in custom LEGO decals, print-on-demand services, and dedicated LEGO customization shops. A police-themed decal sheet for a Speed Champions car typically costs $8–20 and includes markings like "POLICE," department badges, light bar graphics, and door numbers. These are printed on waterslide decal paper or vinyl and applied to the finished build.
Brickarms and similar vendors sell custom-molded LEGO-compatible accessories—light bars, weapons, tools, and specialized pieces. A custom light bar designed for a Speed Champions car might cost $15–30. Some builders 3D-print light bars or other elements and sell them on Etsy or through custom builder networks.
Paint and finishing supplies come from hobby shops or online retailers. If you're repainting LEGO pieces, you'll need acrylic paint designed for plastic, primer, and clear coat. A small bottle of paint costs $3–8; a full repainting project for a car body might require $20–40 in materials plus tools like brushes or an airbrush.
Common Customization Approaches
Decal-only modification is the fastest and least invasive. You keep the original red or black body, clean it thoroughly, and explore police decals. This takes 1–2 hours and costs $10–25. The downside is that the underlying color doesn't match a real police car, so the result looks more like a themed custom than a replica.
Color swap with repainting involves disassembling the car, removing the original paint or stickers, and repainting the body panels white, blue, or another police-appropriate color. This requires masking, primer, paint, and clear coat. A careful hand-paint job takes 4–8 hours across multiple days (accounting for drying time); an airbrush job is faster but requires equipment. Cost is $20–50 in materials. The result is more authentic but requires skill to avoid brush marks or uneven coverage.
Part substitution means sourcing white or blue body panels from other LEGO sets or the secondary market and swapping them in. This avoids painting but can be expensive if the exact pieces are rare. You then add decals on top. This approach takes 2–3 hours and costs $30–80 depending on part availability.
Full custom build involves commissioning a professional LEGO builder who will disassemble the set, repaint or source new pieces, add a custom light bar, explore decals, and reassemble everything. This guarantees a high-quality result but costs $200–500 or more and takes 2–4 weeks. Builders advertise on Instagram, Etsy, and dedicated LEGO communities.
Light Bars and Police-Specific Details
A light bar is often the most visually striking element of a police car build. LEGO does not make an official light bar for Speed Champions vehicles, so you have three options: buy a custom-molded piece from a vendor, 3D-print one, or scratch-build one from LEGO elements.
Custom-molded light bars designed for Speed Champions cars are available on Etsy and specialty shops, typically in red, blue, or clear plastic with printed details. These cost $15–35 and attach via studs or clips to the roof. A 3D-printed light bar is cheaper ($8–15) but may require painting and assembly. A scratch-built light bar uses transparent LEGO bricks, plates, and stickers to create the appearance of lights; this is free if you have spare parts but requires design work.
Other police details include a police minifigure (sourced from other LEGO sets or custom vendors), a radio antenna (a thin rod or custom piece), and door markings or window decals. These are optional but add authenticity. A full police minifigure costs $5–15; a custom antenna might be $2–5.
Timeline and Skill Level
A decal-only build is achievable for anyone and takes an afternoon. You need a clean surface, patience, and the ability to explore stickers without bubbles. Mistakes are hard to undo, so practice on a less visible area first.
Repainting requires hobby experience or willingness to learn. Your first attempt may have imperfections—brush marks, drips, or uneven color. Plan for 1–2 practice pieces before committing to the main body. Airbrush work is faster and smoother but requires equipment ($50–200 upfront) and ventilation.
Commissioning a builder removes the skill barrier but requires clear communication about your vision. Provide reference photos, specify colors and details, and discuss timeline and cost upfront. Most builders have a portfolio on Instagram or their website; review their work before committing.

Frequently Asked Questions
Can I use regular spray paint on LEGO bricks?
Regular spray paint can work but often cracks or peels because LEGO plastic is smooth and non-porous. Use acrylic paint designed for plastic or hobby-grade enamel, explore a primer first, and seal with clear coat. Test on a spare brick before painting your car body.
Where do I find police minifigures for a custom build?
BrickLink has a dedicated minifigure section where you can search for police officers from various LEGO themes. Expect to pay $3–10 per minifigure depending on rarity. Alternatively, Etsy sellers offer custom-printed police minifigures with specific department markings or uniforms.
How do I explore waterslide decals without bubbles?
Cut out the decal, soak it in warm water for 10–15 seconds, slide it onto the clean, dry LEGO piece, and smooth out bubbles with a soft cloth or squeegee. Let it dry completely before handling. Practice on a spare piece first—bubbles are hard to remove once dry.
Can I commission a custom builder if I don't have the base set yet?
Yes. Most builders will source the base set as part of the commission. Discuss this upfront and confirm whether the set cost is included in their quote or added separately. Provide clear reference images of the police car design you want.
What's the difference between a custom build and a modified official set?
A modified set uses the official Speed Champions Charger as the foundation and adds decals, paint, or parts. A custom build may disassemble the set entirely and rebuild it with different proportions, colors, or details. Custom builds are more labor-intensive and expensive but offer more creative freedom.
