BMW M4 xDrive Sway Bars - Front + Rear - Dinan - Adjustable 26mm Front + Rear - 2021–2026. This Dinan anti-roll bar set sharpens response and reduces body roll for a more planted M4 on road or track.

Designed for the G82/G83 M4 xDrive, these 26mm front and rear bars use high-tensile tubular alloy steel to add roll stiffness without excess weight. Compared with stock sizes (22.5mm front, 21.9mm rear), they keep the car flatter, improving mechanical grip and steering precision. The rear bar provides 2-hole adjustability to tune balance. Includes polyurethane bushings and grease. Professional installation is recommended; a subframe drop is required and the typical 9.9 hr install includes alignment.
