Grip and Durability with XRAY 353353 XB8'16 Composite Rear Upright

The XRAY 353353 XB8'16 Composite Rear Upright is a carefully made part designed to improve traction and robustness on challenging tracks. This one-piece upright uses tailored geometry to boost tyre bite and to smooth out impacts from bumpy surfaces. It is reversible for left or right fitment, giving flexibility during setup changes at the track.

Flexible Setup Choices

Use this upright to fine tune behaviour for different layouts and surfaces. The upper roll centre offers three distinct positions and the lower roll centre can be selected in two positions to alter balance. The lower suspension pin comes with two shims so you can tweak wheelbase for the handling you want.

Fine Geometry Control

• Camber: Modify wheel lean to control tyre contact and mid corner grip.
• Upper Roll Center: Three settings to influence roll behaviour.
• Lower Roll Center: Two settings to help maintain stability over rough ground.
• Wheelbase: Use the included shims on the lower pin to make measured wheelbase changes.
