If painting your calipers, I would use the G2 Paint system. That stuff really lasts. It's like a 2-part epoxy kind of paint. And they have quite a few different colors. They sell it at TireRack and I'm pretty sure you can get it on Amazon.com and ebay and other places too.
Is anyone interested in Decals for the calipers? like "FR-S" or "BRZ" or "GT-86" or something else? I can make them in 12 different colors and also a carbon fiber textured vinyl. Though, I don't recommend the CF vinyl for calipers. I already do caliper decals in "Spyder" or "MR2" and pricing would be the same at $10 for a set of 4 decals. If there is any interest, let me know what you would like them to say and I'll add them to my site:
