The Cusco rear lateral link kit with pillowball bushing is specified for 2004–2005 Subaru WRX STI (GD) applications. It replaces the rear-side linkage with a pillowball-equipped hybrid bushing to preserve alignment precision and improve responsiveness. This kit is intended for STI owners performing suspension maintenance or seeking firmer lateral control on supported GD chassis years.
