A Cusco pillowball rear upper mount for GC8 Impreza applications; note it will not fit OEM-style large-spring setups. This pillowball-style rear top mount replaces factory rubber to reduce compliance and stabilize rear suspension geometry under load, improving camber repeatability and rear-end response for drivers seeking firmer handling characteristics.
