Refined Rear Roll Control for the X4

The XRAY 303831 X4 Rear Anti-Roll Bar is a precision-engineered component aimed at cutting body roll and improving mid-corner stability. It is tailored for the X4 series and helps drivers refine rear-end behaviour on varied surfaces.

Designed for a Low Centre of Gravity and Precision

This bar ties into the lower suspension arms to keep the setup compact and support a low centre of gravity. Ball-bearing bulkhead mounts provide smooth articulation and precise feedback under load.

Easy Thickness ID and Height Adjustment

Laser-etched stripes mark the bar thickness so you can identify the correct unit quickly. Height is adjustable with a screw mechanism, allowing rapid tuning to suit track conditions or driver preference.
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 compatible with modified X4 cars?

Generally yes, but check that other aftermarket parts do not block the mount points. It fits standard X4 layouts without interference.

Will it affect traction on loose surfaces?

Changing rear roll stiffness can shift traction; a stiffer rear bar tends to reduce roll and can increase rotation, which may help or hinder grip depending on the surface.

How do I read the laser marks?

The laser stripes correspond to thickness sizes. Compare the stripes to your parts list to confirm you are using the 1.1mm bar for consistent setup records.
