XRAY 343311-H Hard Composite Rear Upright Aero Disc - Race Upgrade  [XR-343311-H]

Race-Grade Rear Upright XRAY 343311-H

The XRAY 343311-H Rear Upright uses a tough composite formulation to lower deflection and sharpen rear-end response. It maintains correct suspension geometry when cornering hard, improving predictability. Built for the RX8E 2023 series, it suits racers focused on consistent handling and lap time improvements.

Durability and Track Reliability

The hard composite construction of the XRAY 343311-H resists wear better than softer uprights, offering longer service life under race conditions. Stiffer uprights help keep suspension readings stable, so your setup changes hold true between sessions. That reliability matters when you are pushing the car hard.

Practical Uses on the Track

This rear upright is useful when switching to a more aggressive setup or replacing worn components without changing geometry. It supports precise ride height and camber adjustments, letting you tune the RX8E 2023 for specific circuits. The XRAY 343311-H is a solid part to have in a race workshop.
