H&R Front Sway Bar - BMW M2/M3/M4 (G87/G80/G82/G83)

OVERVIEW

The H&R Front Sway Bar for the S58-powered BMW M2, M3, and M4 upgrades the front anti-roll bar to sharpen turn-in and reduce body roll while preserving a streetable ride. The larger-diameter front bar increases roll stiffness and improves mid-corner balance over the factory setup. Offered in drivetrain-specific diameters for RWD and xDrive models. Cold-formed from high-tensile spring steel and made in Germany. The matching H&R rear sway bar is sold separately.
