Description
Unlock the true handling potential of your BMW with the Dinan Anti-Roll Bar Set, engineered for the latest G20 3-Series, G22/G23 4-Series, G26 Gran Coupe, and G42 2-Series platforms. Designed specifically for the 230i/M240i (2023–2025), 330i/M340i (2019–2025), and 430i/M440i (2021–2025), this suspension upgrade transforms your driving experience with sharper response, flatter cornering, and enhanced stability.
Factory anti-roll bars are tuned primarily for comfort, often leaving handling performance underdeveloped. Dinan redefines the balance by creating chassis-specific bars that significantly reduce body roll without sacrificing everyday drivability. The result is improved mechanical grip, more precise steering feel, and greater driver confidence whether on winding back roads or at the track.
Built from high-tensile strength tubular alloy steel, these anti-roll bars deliver superior stiffness while keeping weight in check. With a 28mm front bar and a 19mm rear bar, stiffness increases by 50% (front) and 54–66% (rear) compared to stock. The rear bar also features 2-hole adjustability, giving you the flexibility to fine-tune handling balance for comfort or performance.
Each kit includes black polyurethane bushings and grease, ensuring long-lasting durability and reduced deflection compared to rubber factory components. Finished in a durable powder coat, the Dinan Anti-Roll Bar Set is designed for years of high-performance driving.
