H&R Sway Bar Kit – BMW 128i & 135i (E82/E88, N52/N54/N55)

OVERVIEW

H&R's sway bar kit for the E82/E88 1 Series replaces the factory front and/or rear anti-roll bar with a larger-diameter tubular bar, increasing torsional stiffness to cut body roll and sharpen turn-in without stiffening the ride the way lowering springs do. It's available as a Front Only, Rear Only, or matched Front & Rear Set so you can dial in exactly how much of a handling upgrade you want.

Increasing rear roll stiffness relative to front also helps rotate the chassis into corners, a common pairing with H&R's springs or coilovers on the 128i and 135i.
