The "Ford GT" logo has a 9 X 1 (Length to height) ratio. I figured about 4 inches in length would be about right for the calipers. That would put the height at under 1/2 inch. At that size, I'm worried that the gap between the two "racing stripes" that spell the logo would be so small it would be tough to create in a stencil, much less paint without any bleed through.
Then I thought about a self adhesive vinyl decal. But, I don't know if it can stand up to the heat of a caliper. I have a company to make them. I just need some more thoughts or ideas?
