This is the website for Thunder Ranch. While this business no longer exists, the assets are now owned by Rock West Racing, a company currently producing kits for the Speedster, Spyder, RSK and GTS. We are preserving the site for its historical interest. Enjoy your visit, and please come visit us as Rock West Racing!

Welcome to Thunder Ranch, the premiere designers and fabricators of kit cars since 1978. A moment or two spent at our site will introduce you to our exciting line of fiberglass bodied cars and will show you the reason why our work continues to set automotive standards.
