There was awhile back... I don't see it readily now. It may have been in "spot racing" section, IIRC. There was an oval racing series with them too at one point. So keep an eye out, it's actually pretty popular.
I've tried to put a Caterham race together a couple of times, but it's geared sort of funny in stock condition... and my usual pals & I only race tuning: prohibited for the most part. So it's never come together.
I have been considering putting together something with the Suzuki GSX-R/4 Concept '01 ... which happens to be geared quite nicely in stock condition. Don't know if that would get your interest at all though.
Keep an eye out.
