Budwench's old fanfic site - the first Nascar fanfiction site, and also the first to feature my fic. She's not updating it any more, but it's still pretty neat to check out all the same.
Nascar Green Flag Fanfiction - one of the newer sites that cropped up after the demise of fanfiction.net (that cowardly site). They also feature my story, Legend In Motion.
The Pit Crew - I submitted my story to this Nascar fanfiction site over a month ago, and they still haven't posted it. Either they didn't get it, or they're pretending that they didn't. Hmmhmmhmmm (that's me humming)
