    UMI Performance

    Before we built suspension parts, Utmost Machine manufactured precision components for major brands such as Bell+Howell, Corning Asahi, and Sony. Our product line has changed over the years but our dedication to quality remains the same.

    If we can make it in our shop, we do. This means we control almost every aspect of the product, resulting in suspension components suitable for attacking the high banks of Daytona or more importantly, hauling your family.

    Our product engineers and sales team are racers. We race what we sell and use that experience to design and develop our products.

    Our dedicated craftsmen and craftswomen use only the highest quality USA sourced raw materials to build components worthy of your dream car.
