I've been thinking about doing the same thing on my CGM but with flat black stripes. I photoshopped it the other day to see if I liked it. You cant see, but my wheels are Stock RS wheel powder coated gloss black. I figured my car color with flat and gloss black would be 3 good contrasts. What do you think? Also, obviously since this is photoshopped, the stripes stand out a LOT more than they would in real life. I'd hope for them to be a more subtle stripe.
