The H&R rear sway bar (25mm, adjustable, 3‑hole) for 2004–2007 Subaru WRX STI (GD) allows tuning of rear roll stiffness to refine balance and cornering behavior while preserving ride comfort. Forged ends and increased diameter provide quicker response and improved transitional control; the multi‑position mounting offers on‑car adjustability and most kits include Poly/Teflon bushings that prevent squeaks and need no lubrication.
