Product Description

The Eibach E40-20-057-01-11 ANTI-ROLL-KIT is a purpose-built front and rear sway bar system engineered specifically for the BMW G8X chassis (M2, M3, M4). Both bars offer 3-way adjustability, letting drivers dial in anything from a comfortable street setup to an aggressive track balance by fine-tuning front-to-rear roll stiffness. The tubular design keeps weight down while cold-forming, heat-treating, and shot-peening give the bars long-term fatigue resistance. Ideal for RWD G8X owners looking to sharpen handling and reduce body roll without sacrificing daily-driver comfort.
