Refine Rear Roll for Better Corner Exit

The XRAY 303821 - X4 Anti-roll Bar, 1.1 mm, is a tailored component for the X4 2022 line that tightens up rear-end stability. It mounts to the rear suspension arms to sharpen handling characteristics and improve traction under load.

Ball-Bearing Mounting for Consistent Motion

This anti-roll bar uses external ball bearings on the rear bulkheads to ensure smooth rotation and reliable operation. The external mounting makes swapouts and fine adjustments quick, keeping your setup time to a minimum.

Easy ID and Simple Height Setting

Laser-engraved stripes make it simple to pick the correct bar thickness when swapping spares. The height is adjusted via a screw mechanism so you can quickly alter roll stiffness and familiarise your car with different track conditions.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Is this specific to the X4 2022 layout

Yes, it is designed to match the X4 2022 rear suspension geometry. Other years or models might need different linkage or bulkhead spacing to fit properly.

What does the engraving mean

The laser-engraved stripes correspond to the bar thickness, making it straightforward to identify 1.1 mm bars among spare sets during pit checks.

Recommended way to test changes

Change the bar height in small steps and run a few laps after each tweak. Record lap feel and times so you can return to the best baseline setup quickly.
