Racing tires are usually expensive... Adding "racing" to any item usually makes it more expensive (often because it's suppoed to be lighter and more reliable).

My club is sponsored by Schwalbe and we get their Stelvio racing tires for less than what they sell for in stores. I haven't had them for long but so far I like them... Even at regular price, I think they are a little less expensive than the Vittoria Rubino Pro and the Michelin Tires, too.
