H&R Sway Bar Kit – BMW 320i/328i/328d/330i xDrive (F30/F31/F34, N20/N47/B48) & 428i/430i xDrive (F32/F33/F36, N20/B46)

OVERVIEW

H&R's matched front & rear sway bar set increases torsional stiffness over the factory bars on the xDrive-equipped F30 sedan and F32-family coupe/convertible/Gran Coupe, reducing body roll and sharpening turn-in without giving up the ride quality xDrive owners expect. The front bar is two-hole adjustable for street or track roll-stiffness tuning.

H&R sells this as a single part number across the xDrive 320i/328i/328d/330i (F30/F31/F34) and 428i/430i (F32/F33/F36) — these share the same front/rear suspension geometry and subframe mounting points on the xDrive F3x platform.
