On the first generation Rx-7s, the sunroof panel comes off with quick-release tabs like a targa top. At a meet, a guy gave me a spare panel. I was bored and did this in sharpie. IT's kinda like the sharpie lambo/Mr. Clean's ride, only more orderly. I traced a real rotor, so it is actual size. The font, I printed out, then cut up and traced. I might re-do it in real paint rather than sharpie, but it'll b fun to sport this at meets.
