XRAY X1'21 2.5mm Graphite Lower Suspension Arm

The shape of the arm is designed to be more robust for improved durability. The extra material reinforces the arm and prevents it from bending in hard crashes. The arm also incorporates an access window to reach the new front tube for easier installation and tuning.

The arm’s special graphite material with a stronger compound hardness reduces flex, increasing stability and improving drivability in high traction conditions.

The front lower arm also features two mounting positions to set the car’s front width.

The softer front lower arms from previous X1 versions are still available as options and are recommended for use on low-traction tracks, or when using harder front tires, to generate more steering.
