Give your classic musclecar modern handling with UMI Performance! Built using the very latest design and machining technology, UMI Performance also installs and tests every chassis and suspension component it makes to ensure that they perform as designed. UMI focuses on musclecars from the 1960s to today—A-bodies, F-bodies, B-bodies, G-bodies, and Mustangs. Choose from components like crossmembers, panhard bars, control arms, K-members, subframe connectors, and more. Many components fit like stock replacements, so they’re easy to install, but you’ll immediately notice tighter handling that’s easy to tune to your needs.
