UMI Performance makes chassis and suspension parts for GM muscle car and classic platforms — A-Body, B-Body, F-Body (Camaro and Firebird), G-Body, H-Body, X-Body, W-Body, C10 trucks and S10/S15 — plus the 1979-2014 Ford Mustang, the 2015-and-newer Ford F-150, the Pontiac G8, the fifth- and sixth-generation Camaro and the Cadillac CTS-V. Most arms, bars and brackets are offered in a red or a black powder-coat finish.
