Magnetic Door Number for Racing Number

[Alfatango]

Hi has anyone used one for this for CAMS Motorsport Events? Do they pass scrutineering? Do they leave any marks on the car?

I don't know if they pass scrutineering.  It's a long time since I was on the track.

But if you don't need the background, I'd be more inclined to just buy vinyl numbers and stick them straight onto the doors.   If the paint is good, with a good coat of wax, the stickers should come off cleanly.  No chance of them falling off, or moving and scratching the paint

$45.00 plus postage buys a lot of vinyl numbers and you still have to buy the numbers to apply to the magnetic background anyway.

Thanks for the reply. 2 digits in vinyl tends to be around 9 dollars so getting them for both sides for each round will quickly add up. Also this way I dont have to drive around with numbers on the car through out the year (would be better for my street cred ).

I have seen magnetic signage get blown off sedans at Phillip Island and Sandown.  Car is usually black flagged.
Usually need to demonstrate to the Chief Scrutineer the backing panels are secure and wont become a hazard to other cars.
White adhesive numbers on side widows are typically more popular.
The Sup Regs for the event usually define car numbering. 
AROCA (Vic) sells numbers for $3 each - on average around 20 < 30 per event!

I use to cut from a sheet of magnetic vinyl and the race tape edges to prevent losing them,also cut the numbers from a roll adhesive vinyl sheet

Thanks Colin. That was my concern that it flies off at speed. Are the numbers sold at events or can you buy them online?

[Colin Edwards]

Numbers are usually available at all AROCA (Vic) Sprint events.  Normally available for purchase at "Check In" between 07:00 - 09:00.
