XRAY 343311-H Hard Composite Rear Upright for Aero Disc - Precision Chassis  [XR-343311-H]

Precision Handling with XRAY 343311-H

The XRAY 343311-H Rear Upright is engineered in a hard composite to deliver crisper steering response and tighter suspension control. It preserves correct suspension angles under cornering load, helping to keep handling consistent across a race. This part is compatible with the RX8E 2023 family and is aimed at tuners seeking repeatable results.

Why the Hard Composite Matters

Compared with softer uprights, the XRAY 343311-H offers improved resistance to deformation and longer service life. That reduced flex translates to steadier toe and camber values, which matters when fine tuning steering balance. The increased rigidity also helps with precise setup changes.

Tuning for Different Track Surfaces

The upright's stiffness makes it straightforward to tune for high grip or low grip tracks by adjusting roll centre and shock settings. Use it when you need a stable rear end that reacts predictably to setup tweaks. The XRAY 343311-H is a solid choice when chasing consistent handling across varied conditions.
