H&R Sport Sway Bar Kit – BMW M3/M4 xDrive (G80/G82/G83, S58)

OVERVIEW

H&R's Sport Sway Bar Kit for the xDrive-equipped G80 M3 and G82/G83 M4 upgrades both the front and rear anti-roll bars over the factory units, increasing torsional stiffness to reduce body roll under hard cornering. A stiffer bar keeps more of the tire's contact patch planted through a corner, sharpening turn-in and giving the chassis a flatter, more connected feel without touching ride height or spring rate.

The kit is a direct bolt-on using the factory mounting locations and reuses the factory end links, and both bars are multi-hole adjustable so the front-to-rear roll-stiffness balance can be tuned to the driver's preference. This is the xDrive-specific part number, engineered around the all-wheel-drive front subframe and suspension geometry; the rear-wheel-drive M3/M4/M2 take a different H&R part number (72616-2).

TECH RESOURCES

• None. H&R's sway bar kit ships complete with the bushings and hardware needed for installation; the factory end links are reused.
• Installer-supplied tools: jack and stands, standard hand tools, and a torque wrench.

Installation

• Illustrated fitting instructions are included in the box with the sway bar kit. H&R does not publish a separate per-application installation PDF for this sway bar; the technical sheet linked below covers spring-specific topics (bumpstop trimming, spring identification) and is not applicable to this sway bar.
• H&R Warranties & Claims (PDF) — official H&R warranty terms, coverage periods and claim procedure.

Notes

• Fitment confirmed against multiple retailer listings (eBay/x-ph, Gumotorsport, R/T Tuning) for part 72616, all titled for the "22-23 BMW M3/M4 Competition xDrive G80 (AWD)" platform. This is the xDrive-specific counterpart to part 72616-2 (RWD) — do not use on a rear-wheel-drive M3/M4/M2.
