    UMI Performance 2521-B Details

    UMI's rear trailing arms for the fifth generation Camaro utilize our Roto-Joint technology for a bind free performance and quiet comfortable ride quality. The Roto-Joint design is a pivot ball lined with a greaseable delrin race designed to offer 28 degrees of total unrestricted movement, more than adequate for a bind free, low friction operation. The Roto-Joint design improves performance over the factory rubber and aftermarket polyurethane bushings by allowing the suspension to articulate correctly, and provide precision handling. The installed UMI Roto-Joint allows rear end free movement when high handling, auto cross or road race is a concern while still being a 100% streetable setup. The installed delrin race, which lines the spherical ball, absorbs shock and road noise for a quiet and smooth operation on any street or track driven vehicle. The rear toe rods control the camber alignment of the rear end preventing the tire from moving inward or outward during suspension load. The factory toe rods are made from flimsy stamped steel and feature soft rubber bushings causing deflection which leads to erratic handling, poor traction and possible rear tire wear. Replacing the factory arms with heavy duty toe rods makes for a more stable suspension, improved traction and better braking. Toe rods are a direct bolt in and installation time is less than an hour using basic hand tools.
