H&R Adjustable Sway Bar Set – BMW M2/M3/M4 (F80/F82/F87, S55/N55)

OVERVIEW

H&R's Adjustable Sway Bar Set for the F80 M3, F82/F83 M4 and F87 M2 platform replaces the factory front and rear anti-roll bars with larger-diameter, hollow tubular bars engineered to increase torsional stiffness and cut body roll in hard cornering. Reducing body roll keeps the contact patch flatter through a corner, sharpening turn-in and giving the chassis a more direct, connected feel without touching ride height or spring rate.

Both the front and rear bars are multi-hole adjustable, so the roll-stiffness balance between front and rear can be tuned to taste — more front bar sharpens turn-in and adds understeer, more rear bar rotates the car into corners faster. H&R manufactures the bars from cold-formed, hollow steel tubing and finishes them in a durable protective coating.

Sold as a Front & Rear Set, or as standalone Front Only / Rear Only bars for builders upgrading one end of the car at a time or replacing a bar individually.
