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.

Will this part fit all X4 variants?

Yes. The XRAY 302143-M - X4 upper arm is made to suit the full X4 series for the front left and rear right positions, matching standard mounting points.

How does medium stiffness change handling?

Medium stiffness improves midcorner grip by allowing controlled flex, which can smooth transitions and reduce snap over uneven surfaces compared to very stiff arms.

Any setup tips after fitting the arm?

After installation, check toe and camber under load and run a few laps to assess balance; small shock or swaybar tweaks often pair well with this arm.
