UMI’s 2258-1R Rear Coilover Kit is the ultimate race-focused solution for 6th Gen Camaro owners demanding maximum rear-end control, consistency, and track tuning capability. Designed for serious road race, time-trial, and national-level autocross builds, this package eliminates the factory divorced spring setup. By pairing stiff 550 lb/in springs with Viking Crusader double adjustable shocks, it delivers the robust platform support required for running high-grip tires, aerodynamic upgrades, and aggressive track alignments. Built for 2016–2024 Camaro models, the 2258-1R system integrates seamlessly into the chassis using UMI’s extreme-duty double-shear upper mounts. The coilover design provides precise ride-height and corner-weight adjustments to optimize cross-weight and rake. With its direct bolt-on installation using factory lower control arm points and zero welding required, this USA-engineered kit allows you to quickly dial in compression and rebound to master any track surface.
