Your exact event belongs in the review.
The quote checks official number-board and badge supply, series sponsor decals, event updates and your exact body configuration.
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.
