High grip rear lower arm for consistent lap times

The XRAY X4 CFF Carbon-fiber Fusion Rear Lower Arm - Hard is tailored for the left rear location, combining a carbon fibre plate with composite material to deliver robust support with tuned compliance.

Engineered fusion for stable chassis behaviour

XRAY's fusion technique creates a stiff central section with calculated flex elsewhere, yielding suspension arms that keep handling predictable across varying track temperatures and grip levels.

Preferred choice for carpet and high traction asphalt

On carpet or high grip asphalt the hard version reduces unwanted movement at the rear, helping to maintain a steady line through corners and improving mid-corner stability.
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.

How will this arm affect mid-corner balance?

The arm lowers lateral deflection, which tends to stabilise mid-corner behaviour. Expect a firmer rear end; adjust front settings if the car feels too tight in turns.

Is this compatible with aftermarket hinge pins?

Compatibility depends on pin diameter and chassis layout. Most X4-compatible aftermarket pins will fit but always confirm clearances before final assembly.

Should I change tyre compounds with this arm?

You may find a slightly different tyre choice helps balance the stiffer rear; try softer front or different rear compounds to match the increased rear stiffness for best lap times.
