The Superpro rear sway bar for the 2009 Subaru Forester X Premium is a 20mm, three-position adjustable bar that reduces body roll and improves cornering control. Its multiple positions let you alter rear stiffness to favor rotation or stability for autocross or track use, raising sway rates roughly 30–50% over OE when shifted outward. Superpro sizes and forms the bar for precise fitment and easy, tool-friendly adjustability.
