Now, I noticed that there were several threads for autoracing mangas but I just rather like racing in general as a plot. No need for it to be cars(nothing wrong with cars though). I mean there's cycling and foot racing and lots of things, like space ships or robots. I'm good with anything(yaoi, yuri, ecchi, etc.) preferably no smut or hentai though.

for example Overdrive or Capeta though I don't really think I need examples of what racing is.

Only racing manga I know is Initial D..
