Reduce body roll and improve mechanical grip on the 2006-2010 BMW M5/M6 E60/E63/E64 with the Dinan Front Roll Control System. The system relocates the factory anti-roll bar mounting points so the stock bar acts more like a stiffer bar, improving stability and cornering control while retaining a controlled level of body movement. Designed for use with Dinan's 21mm Adjustable Rear Anti-Roll Bar for proper balance when front and rear tire widths differ by less than 30mm. Features reduced body roll, increased mechanical grip, and improved stability at the limit. Part number: D133-0495.
