So the rules say white numbers on black. I see lots of cars with different color arrangements. We'd like to do black numbers on white background but don't want to fail tech and have to deal with it Friday night. Thoughts? Experience?
Make sure they are large and contrasting colors to the background and you should not have any issues. They need to be read by the corner workers, starter and control tower.
Mine follow the rules so well that the corner workers call our numbers all the time for no reason. Lol
Black on white has been fine for us for 5 years... Although, they probably don't even call our number... Just say, "that damned yellow car with handprints f-ed up again."
We have black on white. No problems. They're BIG.
It's always best to check with us beforehand if you have any doubts about your car numbers. Try to imagine that you're a 75-year-old flagger with cataracts and a vicious Five O'Clock Vodka hangover, squinting at car numbers through a cloud of dust and oil smoke with the sun in your eyes. Would the numbers on your car be decipherable under those conditions?
The main thing is to have it contrasting. Could help if you go slightly larger than the minimum for the text, and not have a lot of other words or designs going on around it so it doesn't blend in.
Choose a straight forward block font, nothing fancy.
Also, do not use stencils or fill in the gaps that typical stencils leave.
Don't quote me on this but...I think a prior version of the rules stated the numbers should be either black on white or white on black. We started in '08 with a white car so the numbers were black...

When we switched to a red same kind of car, it was easier to mask over the numbers and paint the white doors and hood red than it was to skin out the red doors/hood...

Tech never said we had to use a black background on the red car.
So, to quote you on that....
Don't quote me on this but...I think a prior version of the rules stated the numbers should be either black on white or white on black.
Yes, at the very least the 2011 version of the rules stated "Numbers must be white on black background or black on white background--all other designs must be approved in advance by the Organizers."
I have to admit I hadn't noticed the change in wording to only white on black before now.
This is the number in question. 12"
No you may not buy those SWEET 14" wheels that came with our $300 powerhouse 
I have those same wheels in 15s if you are looking for more.
If you follow our car-number rules exactly, you will have no hassles. If you want to deviate from those rules to match your theme, we might cut you some slack, but no promises made. That's why it's best to email me or Jeff Glenn or John Pagel with your idea before you go to all the hassle of putting any work/money into it.
