XRAY 363112-M Medium Rear Lower-Right Suspension Arm for XB4  [XR-363112-M]

Rear performance upgrade for XB4 with XRAY 363112-M

The XRAY 363112-M composite suspension arm is made to refine the rear behaviour of XB4 series cars. Located at the rear lower right position, this medium-hard unit gives a controlled mix of compliance and support suitable for varied circuit conditions.

Large C-hub and adjustable geometry

The arm features a large C-hub opening to allow meaningful wheelbase adjustments. It supports multiple shock mounting positions so tuners can change shock angles for better traction and faster corner entries. The design also accepts an optional front anti-roll bar to further tune balance.

Three hardness choices for track tuning

This part is offered in medium, hard, and graphite variants so drivers can match arm stiffness to grip levels. The medium 363112-M is aimed at mixed-surface use where a compromise between grip and steering precision is needed.
