#67 and #68 have new fonts for both words for a cleaner look, easier readability and less "baseball". To further accentuate the K, I extended it to house the word racing and the subtle checkered flag.
Can you add the font from #68 to the design in #50? I like the font, but the connection and line look too much like a hockey stick. Sorry, I know this is a lot of sports references ;-)
