H&R Sport Sway Bar Kit – BMW M3/M4 RWD & M2 (G80/G82/G83/G87, S58)

OVERVIEW

H&R's Sport Sway Bar Kit for the rear-wheel-drive G80 M3, G82/G83 M4 and G87 M2 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 rear-wheel-drive part number; the xDrive-equipped M3/M4 take a different H&R part number (72616).

SPECS

• Front bar: 32mm, hollow, multi-hole adjustable
• Rear bar: 27mm, hollow, multi-hole adjustable
• Construction: cold-formed tubular steel, protective finish
• Increases torsional stiffness front and rear versus the factory sway bars to reduce body roll
• Does not change ride height, spring rate, or damping
• Sold as a complete Front & Rear Set only
• Rear-wheel-drive application only — a separate H&R part number (72616) covers the xDrive M3/M4

PARTS INCLUDED

• H&R front and rear adjustable sway bars
• New mounting bushings and hardware included
• See the fitting instructions supplied in the box for the full bill of materials

TECH RESOURCES

Additional Parts Required

• 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

• Confirmed as a genuine single part number, not a bundling error: retailer itsnotstock.com lists part 72616-2 explicitly as "H&R Front & Rear Sway Bar Kit for G80 M3 RWD, G82/G83 M4 RWD & G87 M2 RWD" — one kit across all three chassis. This is consistent with the G87 M2 being RWD-only from BMW with no factory xDrive option, so it shares the same rear-wheel-drive suspension geometry as the RWD-configured G80/G82/G83.
