The UMI Corner Max lower a‑arm P/N 2655 is a coilover‑only race upgrade for 1970–1981 Camaro and Firebird applications. Removable lower mounts permit spring changes without separating ball joints, the lower ball joint is relocated to add up to 4 degrees of caster, and Delrin bushings plus double‑shear coilover and sway‑bar mounts improve camber curve, roll‑center, and straight‑line stability for track and street use.
