If you missed the new Chevrolet Track Car Concepts unveiled at SEMA, you missed some of the most interesting enthusiast-oriented things to come out of the Bowtie in quite some time. But fear not: you'll get a solid walkaround (with some excellent visuals) of both cars in the video below.

Check out these links to learn more about the Z06X Track Car Concept and the Camaro SSX Track Car Concept. The bad news? GM doesn't have plans to produce limited volumes of either of these. Instead, they're intended to show enthusiasts what's possible with GM Performance Parts accessories and some serious elbow grease. Oh, and some help from Pratt & Miller.
