Hardrace Rear Sway Bar 28mm for BMW 5 Series G30/G31 2017-2024 and BMW 7 Series G11/G12 2015-2022
Hardrace's 28mm rear sway bar sharpens the handling of the BMW 5 Series G30/G31 2017-2024 and BMW 7 Series G11/G12 2015-2022 by cutting body roll and giving more control over the car's balance.
It bolts into the standard mounts, making it an easy upgrade for fast road and track use.

Installation
Support the car safely on a ramp or axle stands. Undo the drop links and bush brackets and remove the original bar. Fit the Hardrace bar with its bushes, refit the brackets and links, and tighten to the vehicle manufacturer's torque figures with the suspension loaded at normal ride height. No wheel alignment is needed for the bar alone. We recommend professional fitting.
Upgrade Further
Do I need an alignment after fitting?
No. An anti-roll bar does not change camber, toe or castor. An alignment is only needed if you change ride height at the same time.
Can I reuse my standard drop links?
Yes. On lowered cars, adjustable drop links let you set the bar level at rest so it is not pre-loaded.
Will it make the ride harsher?
A stiffer bar is felt mainly in corners and over single-wheel bumps. Ride over even bumps is largely unchanged.
Should I fit the front bar too?
Upgrading both ends cuts roll at both axles while keeping the balance closer to standard. Fitting one end only shifts the balance.
Will it fit my car?
It is listed for the models in the Fitment section. If your car has a different engine or drive layout, check with us before ordering.
Is it road legal?
Yes, it is a bolt-on suspension part for road and track use. Tell your insurer about any modifications.
