What Are the Custom Race Door Number Circle Decals?
These are precision die-cut 20" diameter circle decals featuring your custom race number, designed to mount on the driver and passenger doors of any vehicle. Inspired by classic and modern motorsport liveries — think IMSA, SCCA, Group A, vintage Le Mans — they transform a street car, track build, or show car into something that looks like it just rolled off the paddock.
Each set includes two circles, one for each side of your car. You choose the number, the circle background color, and the number color, giving you full control over the look. Whether you're matching your team colors, recreating a famous historic livery, or just want a black-on-white classic look, we cut it custom for you.
The vinyl itself is premium cast — the same grade used in professional vehicle wraps and racing graphics. It's UV-stable, weatherproof, and built to last years outdoors without fading, cracking, or peeling.
Key Benefits
- True race-car presence — the 20" diameter fills a standard door panel the way real motorsport graphics do, not the undersized look you get from generic stickers
- Fully custom — your number, your circle color, your number color. Match your team, livery, or personal style
- Premium cast vinyl — the highest grade automotive vinyl available, rated for 5–7 years of outdoor durability
- Bold racing typography — clean, high-contrast numbers designed to read clearly from a distance, exactly like pro race liveries
- Air-release adhesive — makes installation dramatically easier with no trapped bubbles, even for first-timers
- Universal fitment — works on any vehicle make and model, from a Porsche 911 GT3 to a Miata track build to a Mustang autocross car
Why Your Track Build Deserves Authentic Race Numbers
There's a reason real race cars use circle numbers — the format is mandated by most sanctioning bodies because it's the most legible way to display car identification at speed. Whether you're actually competing in HPDE events, time attack, autocross, or you're just building a tribute car for the street, the circle format instantly communicates "this is a serious car." Skimping on size or quality kills the effect — undersized numbers look like decoration, not livery.
Quality matters too. Cheap calendared vinyl shrinks, fades, and cracks within a season. Our cast vinyl conforms to body curves, resists UV yellowing, and holds its color through years of sun, rain, and track sessions. If you're investing in a build worth photographing, the graphics should match the effort. Looking for more ways to dial in the look?

What's Included & Installation
Each order ships with two precision-cut 20" circle decals (one for the driver side, one for the passenger side) along with detailed application instructions. To order, just add the product to your cart and use the order notes to specify your race number, circle background color, and number color — we'll handle the rest.
Installation is straightforward: thoroughly clean and degrease the door surface with isopropyl alcohol, use masking tape to mark your final position, and apply using the wet method (a light spray of soapy water lets you reposition before squeegeeing). Squeegee firmly from the center outward to push out water and air, then let it cure for 24 hours before washing. If you'd rather have a professional handle it, any reputable wrap or detail shop can install these in under an hour.
