HM: "KTA123 is a complete kit featuring 4 x Whiteline Adjustable Control Arms pre-fitted with low-compliance polyurethane bushes. Whiteline designed this kit specifically to modify the factory camber, toe and track settings on the rear suspension of a Subaru Impreza STi. Benefits include increased precision and range of adjustment, and the heavy-duty materials used further enhance the direct connection between the body and the rear suspension, resulting in more predictable dynamic vehicle behavior.
