Familiar? Yes. Limited availability. Typically people have to keep bugging the guy to make the parts since it isn't a full-time gig for him so be prepared to wait although now I see he lists "in stock" parts. Occassionally for sale on ebay. Part I saw (Callasports' carbon fiber front bumper spoiler) looked like a decent quality wet layup. I'm not sure I'd pay $100 more than an oem front bumper spoiler for a fiberglass one that is so similar but the rear skirt is an option for those in the US looking for the style.
