Overview

Dinan Anti-Roll Bar Set for BMW M2 / M3 / M4 (xDrive) 2021-2026

Instructions - D120-0645.pdf

Note: Dropping of the subframe is required so professional installation is highly recommended. Installation time (9.9 hrs) is inclusive of alignment.

Experience precision-engineered handling with Dinan Tuned Anti-Roll Bars, designed to transform your BMW's cornering dynamics. By replacing the softer factory bars with larger, stiffer units, this upgrade dramatically reduces body roll to increase mechanical grip and driver confidence. The result is a flatter, more responsive, and planted feel—ideal for spirited driving on winding roads or the track.

Key Features:

Increased Size & Stiffness: Features a 26mm front bar (vs. 22.5mm stock) and a 26mm rear bar (vs. 21.9mm stock). The front bar is 16% stiffer, while the rear bar is 35-48% stiffer to aggressively reduce body roll.
Adjustable Handling Balance: The rear bar includes a 2-hole adjustment, allowing you to fine-tune stiffness and handling characteristics to suit your driving style or environment.
Premium Lightweight Construction: Made from high-tensile strength alloy steel using a tubular (hollow) design for maximum strength with minimal added weight.
Enhanced Driving Dynamics: Delivers less body roll, more mechanical grip, and greater stability at the limit for a more connected and controlled driving experience.
Complete Kit: Includes all necessary polyurethane bushings and grease for installation.
