Motorsport Number Round Decal Sticker Set | Racing Decals

Description

A round motorsport number decal set for adding competition-style door numbers to your track, autocross, or show build. Printed on cast vinyl in your choice of matte, gloss, clear, or static cling finish.

Round Racing Number Decals for Track Days and Shows

This motorsport number round decal set gives your car the classic competition look, whether you run autocross weekends, HPDE events, or just want a motorsport theme for your street build. The round panel design echoes the number plates used in organized racing, so your door numbers read clearly from a distance. Each set is printed to order in our shop and cut with a contour that follows the round shape, so there is no background square to trim away. Choose the width that matches your class rules or your visual preference, apply one to each door, and you have a finished motorsport layout in minutes. It pairs well with other racing decals from our Racing Stripes & Flame Decals collection if you want a fuller livery.

Choose Your Size and Finish

Sets are offered in widths from 12 to 48 inches, measured across the round decal at its widest point. Smaller sizes suit doors on compact cars, rear quarter panels, or helmets and toolboxes, while the larger widths make a bold statement on full-size doors or trailer panels. Pick the finish that matches your build: matte for a low-sheen, painted-on look; gloss for a vibrant, show-ready shine; clear for a subtle application over existing graphics; or static cling for a temporary number you can reposition and remove without adhesive residue. Static cling is a popular choice for weekend racers who only run numbers during events and store the decals between sessions.

How to Apply Your Door Number Decals

Application works best on a clean, dry surface above about 60 degrees Fahrenheit. Wash the door panel, remove any wax with isopropyl alcohol, and let it dry fully. Peel the backing, position the round decal using the top edge as your guide, and press from the center outward with a squeegee or credit card to push air toward the edges. The contour-cut edge means there is no carrier film to remove after pressing, so the number sits flat immediately. For static cling, lightly mist the surface with water before placing the decal, then squeegee the moisture out. Take your time aligning the pair so both doors match in height and position.

Care, Removal, and Ordering

Once applied, the adhesive vinyl versions hold up to normal washing; avoid direct pressure washing on the edges and skip high-heat drying cycles. To remove, warm the decal gently with a hair dryer and peel at a low angle, then clean off any remaining adhesive with isopropyl alcohol. Static cling peels off by hand with no residue and can be stored on its original backing for reuse. Each set includes decals for both sides of the vehicle so your numbers match. Because every set is printed after you order, double-check your number choice and size before checkout. Questions about sizing or finish selection can be sent to our shop before you buy, and we are happy to help you pick the right width for your doors.

Frequently asked questions

How do I choose the right size for my doors?

Measure the flat area of your door panel where you want the number, then choose a width that is smaller than that space. Many drivers use 12 to 18 inch rounds on compact cars and 24 inch or larger on full-size doors.

Can I use these for an actual race event?

Many organizers accept vinyl door numbers, but rules vary by series and class. Check your rulebook for minimum number size and contrast requirements before ordering.

Will static cling work on the outside of my car?

Static cling is designed for smooth exterior glass and painted panels. It applies with a light water mist and can be removed and reapplied, making it a good option for weekend-only use.
