BMW 330i Sway Bar - Rear - Dinan - 15.8mm (2006-2013). A Dinan rear anti-roll bar designed to cut body roll and temper understeer for clean, predictable handling.

Designed for select E8x/E9x BMWs, the 15.8mm bar is tuned per chassis to keep the car flatter in corners and add mechanical grip. On E90 330i and other models with a 13mm stock rear bar it is 118% stiffer; on 15mm cars it is about 23% stiffer. For proper balance on RWD vehicles, pair with Dinan’s 28mm front sway bar (D120-0530). Not compatible with 328xi. Please confirm fitment before purchase.
