The Dinan D120-0491 Adjustable Rear Anti-Roll Bar is designed for 2006-2010 BMW M5/M6 applications using the E60/E63/E64 chassis.

The bar is 21mm in diameter and offers three adjustment positions. Dinan designed it to reduce body roll, increase mechanical grip and improve stability near the handling limit.

Dinan specifies this rear bar for use with its D133-0495 Front Roll Control System for proper balance on vehicles with less than a 30mm difference between front and rear tire width.
