Precision Handling with XRAY Carbon Upper Arm

The XRAY 302134-S X4 CFF Upper Arm in soft form improves steering accuracy and side traction on low grip surfaces like carpet and aged asphalt. Designed for the front right and rear left locations, it is a focused upgrade for drivers chasing improved cornering balance.

Design and Composite Traits

Built from CFF (Carbon Fiber Fusion), the arm aims to provide repeatable flex characteristics and reliable handling feedback. Its contour maintains necessary inner shock clearance while supporting forces that aid forward and lateral grip. The softer material boosts mechanical traction but can be less robust than harder choices.

Setup Advice for Slick Tracks

On very low to low traction tracks the arm reduces radial play and helps tyres work more effectively through the turn, offering a more precise feel. It is especially useful when small steering inputs must translate into consistent direction changes.
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.

Which tracks benefit most from this arm?

Very low to low traction surfaces such as older carpet or scuffed tarmac see the biggest handling gains from the soft arm.

Will this change my suspension tuning?

Yes, you may need to adjust camber and toe to get the best balance as the arm alters side bite and steering response.

How do I check for wear?

Inspect mounting holes and contact areas after each session; any cracks or elongation indicate replacement is needed.
