Dinan Adjustable Sway Bar Set 28mm & 19mm - BMW G22 / G23 / G26 430i / M440i

Factory anti-roll bars on the BMW G22 and G23/G26 platform are sized for ride comfort, not cornering authority. Dinan replaces both with hollow high-tensile alloy steel bars tuned specifically for the G-platform's weight distribution: a 28mm front bar (vs. stock 26.1mm) and a 19mm rear bar (vs. stock 17.8mm). The result is 50% more front stiffness and 54-66% more rear stiffness — enough to meaningfully reduce body roll without introducing the instability that comes from oversized bars.

The rear bar is 2-position adjustable, letting you fine-tune the understeer/oversteer balance for track days, canyon runs, or daily driving. Tubular hollow construction keeps the weight addition minimal while delivering a step-change in cornering capability. Polyurethane bushings and grease are included.
