BMW 335is Sway Bar - Rear - Dinan - 15.8mm (2011–2013). A purpose-built rear anti-roll bar that sharpens chassis response and boosts confidence while remaining street-friendly.

Engineered and tuned by Dinan specifically for the E92/E93 335is, this 15.8mm rear bar reduces body roll and curbs understeer so the car stays flatter and generates more mechanical grip. Depending on factory equipment, stiffness gains are up to +118% over 13mm bars or +23% over 15mm bars. It integrates well into staged suspension builds and, for proper balance on RWD cars, Dinan recommends pairing with the 28mm front sway bar (D120-0530), especially on vehicles with a limited-slip differential or a significant rear-tire stagger.
