Transform your BMW's cornering character with Dinan Tuned Anti-Roll Bars, engineered to deliver a crisper, more responsive driving experience. By significantly reducing body roll compared to the comfort-oriented factory bars, these upgrades keep your vehicle flatter through turns, increasing mechanical grip and driver confidence. Whether on a back road or track, the result is a more planted, stable, and engaging connection to the road.

Key Features:

• Increased Size & Stiffness: Features a 28mm front bar (vs. 26.1mm stock) and a 19mm rear bar (vs. 17.8mm stock). The front bar is 50% stiffer, while the rear bar is 54-66% stiffer to dramatically combat body roll.

• Fine-Tuned Adjustability: The rear bar includes a 2-hole adjustment, allowing you to tailor handling balance and stiffness to your driving environment or comfort preference.

• Premium Lightweight Construction: Made from high-tensile strength alloy steel using a tubular (hollow) design for maximum strength with minimal weight gain.

• Enhanced Driving Dynamics: Delivers less body roll, more mechanical grip, and greater stability at the limit for a more planted and confident feel in every corner.

• Complete Kit: Includes all necessary polyurethane bushings and grease for installation.
