PLAN THE WHOLE CAR
Every position.
Accounted for.
Measure a clear area at each location before settling on a layout. A door handle, body crease, trim strip, or small front/rear area can change the available footprint.
Position reference: 2026 BCCR v1.4 · §§9.7–9.8. For magnetic placement limitations, read Magnum’s installation guidance.
Every required position will be recorded on the quote and dimensioned proof. The car preview is an artwork concept.
Position list is a planning diagram, not an inspected installation or a scale drawing.
Use the authorized graphics.
The official BCCR and event instructions control. We verify the authorized supply route and complementary graphics before quoting; no substitute official card is implied.
Before a production proof
- Check your registered number and any class or run-group identifier.
- Confirm current event requirements and required official decals.
- Measure clear width and height on the actual car.
- Record the finish and check the selected attachment material.
We check the actual characters, stroke widths, positions and supplied fit measurements on the production proof. The on-screen car illustration does not complete those checks.
A few useful answers.
Can I order if I do not have the complete rulebook?
Yes. Send the event registration link and what you know. We will research the identification requirements and keep the request open until the missing details are resolved. Printing starts only after the quote and production proof are approved. Official reference ↗
Can a magnetic kit work on every car?
No. It needs a suitable magnetic surface and full contact; aluminum, fiberglass, and carbon-fiber panels are not suitable magnetic substrates. Check the actual mounting area and finish. Magnum care and application guidance · Our material guide.
Does this include a guarantee of event compliance?
Our Race Ready service checks number-graphics requirements and provides a correction promise for our documented work. The organizer retains final approval; graphics do not certify vehicle classification, equipment or technical inspection. See our service terms.
