BMW 4 Series F32 F33 F36 RWD 6‑cyl Sway Bar Upgrade by H&R

Transform the way your BMW 4 Series turns in and grips with this premium H&R anti‑roll upgrade. Engineered in Germany for the F32 Coupé, F33 Convertible and F36 Gran Coupé rear‑wheel drive six‑cylinder models, this front and rear stabiliser bar set is a proven way to cut body movement, sharpen steering response and unlock confident, fast‑road and track‑day handling without ruining ride comfort.

We have installed this kit on customer cars and our own builds, and the feedback is consistent – flatter cornering, better balance and a more connected feel. If you want a simple, high‑impact suspension upgrade that works brilliantly on UK roads, this is it.
