Dinan 32mm Lightweight Tubular 4-Way Adjustable Front Anti-Roll Bar (Sway Bar) for BMW M3 F80 & M4 F82 F83 (F8x)

Dinan front roll control bar for BMW F8x M cars

Unlock sharper handling and flatter cornering on your BMW M3 F80 or M4 F82 F83 with Dinan’s 32 mm hollow front stabiliser. This four‑position adjustable swaybar is engineered specifically for the F8x platform to trim body lean, boost front axle grip and deliver a more planted, confidence‑inspiring drive on fast road and circuit use, all while saving weight over the factory item.

We have fitted and driven this upgrade ourselves at MJ Modifications, and customer feedback mirrors our experience: quicker turn‑in, steadier mid‑corner balance and superior traction when you lean on the car. Dial in the stiffness to suit your tyres, alignment and driving style, then enjoy consistent, predictable response on B‑roads and track days.
