Prototype Build

Pratt Miller was founded in the ultra-specialized prototype world of sportscar racing, building one-off, state of the art race cars. Since then the team has grown in size, capability and portfolio, however Prototype Build and the level of precision that goes along with it, is still very much at the core of what Pratt Miller does. From machining highly complex components to full vehicle builds, Pratt Miller can take your vision to reality.
