Description
Tune roll resistance on 2006-2010 BMW M5 with the Dinan Adjustable Rear Sway Bar.
An anti-roll bar couples suspension movement across an axle, resisting body roll in cornering. Bar size and adjustment change that axle’s contribution to the car’s balance; the best setting depends on the complete spring, tire and alignment combination.
Technical details
- Bar diameter: 21mm.
- Adjustment: selectable roll-stiffness settings.
- Listed vehicle application: 2006-2010 BMW M5.
- Manufacturer part number: D120-0491.
Fitment and installation
- Confirm drivetrain and chassis compatibility; xDrive and rear-wheel-drive bars may use different packaging.
- Set adjustable end links without unwanted preload and verify clearance through suspension movement. Choose settings incrementally rather than assuming maximum stiffness gives maximum grip.
- Dinan specifies pairing with front roll-control system D133-0495 for the intended balance.
