The factory rear sway bar on the C34 Stagea 260RS and RS-FOUR leaves the wagon feeling soft and loose during enthusiastic driving or when loaded. SuperPro’s 22mm Heavy Duty Rear Sway Bar (part sprRC0010RZ-22) is a thicker 3-position adjustable blade-style bar that lets you dial in the exact rear roll stiffness you need — from comfortable daily cruising to sharp, planted performance on twisty roads or track days.

This complete Australian-made kit includes the robust 22mm blade bar, heavy-duty adjustable links, performance bushings, and all mounting hardware. The upgrade delivers noticeably flatter cornering, stronger rear-end support, and better overall balance while keeping the Stagea’s practical ride quality intact.
