UMI’s Corner Max front end kits are a comprehensive system with our best corner carving parts under one easy to find part number. The Corner Max system combines geometry corrected a-arms with tall ball joints, higher rate springs, UMI rebound adjustable monotube shocks, heavy duty sway bar and a bump steer kit. The foundation of the kit includes our coilover-only lower a-arms featuring caster improvement, tall ball joints, and the ability to remove the spring and shock without taking the spindle apart. The upper a-arm features rod ends for smooth operation and the ability to adjust without shims. The 1-¼” sway bar upgrade complete with UMI’s fabricated end links reduces body roll and helps speed transitions. Racing coilover springs are paired with UMI’s rebound adjustable coilover monotube shocks. Fine tuning is accomplished with a UMI bump steer kit. The Corner Max kit is built to make the stock GM clip work as well as it possibly can with a true bolt-on kit. All UMI Performance parts are fabricated and raced with pride out of Philipsburg, PA – USA. Race proven on the UMI Green Machine.
