Make some fantasy rule that makes carbon have no advantage. Ill still want/do it because I like the look.

You old guys I think just get bored and start making rules up that don't need to be in place (or in your case dad, writing out long winded responses with a bunch of hooplah most don't understand or read lol).... You guys need a secondary hobby for when you're not at the racetrack that doesn't include racing ********.
