Traction upgrade using XRAY CFF extra soft upper arm

The XRAY 302144-XS upper arm is built to boost handling where grip is limited, such as on asphalt and carpet circuits. Made from CFF (Carbon Fiber Fusion), the arm balances flexibility with strength to improve both lateral and forward traction.

Structure that improves handling

This extra soft arm uses a thinner carbon layup to increase mechanical grip and enhance side traction. The shape is designed to wrap around the inner shock location, keeping clearance while remaining sufficiently robust for race use. The result is crisper steering response and more controllable transitions.

Fitment and racing trade offs

Made for the X4 chassis front left and rear right positions, the XRAY 302144-XS reduces radial play for tighter precision on track. Its softer nature can be more prone to damage, but for many drivers the handling gains on low-grip surfaces justify the compromise.
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 fit every X4 variant?

Yes. The XRAY 302144-XS is compatible across X4 series cars where a front left or rear right extra soft upper arm is required.

What handling gains should I expect?

Expect increased mechanical traction and improved side bite, which helps rotation and corner entry on low-grip surfaces like carpet or worn asphalt.

Any tips for durability?

Check for impact damage after hard hits and avoid overtightening mounting hardware. If you push a softer arm hard, inspect it regularly and keep a spare on hand for races.
