BMW 328i Sway Bar - Rear - Dinan - 15.8mm (2006–2013). A Dinan‑tuned rear anti‑roll bar that tightens response and cuts body roll on RWD models.

Designed for BMW E9x/E93 platforms, the 15.8mm rear bar reduces understeer and keeps the chassis flatter for improved mechanical grip and driver confidence. For proper balance, Dinan advises pairing with the D120-0530 28mm front sway bar on RWD cars, especially when equipped with a limited-slip differential or a staggered setup with rear tires 20mm wider. Not compatible with 328xi.
