Sharper Cornering with XRAY 343311-H

The XRAY 343311-H Rear Upright is built from a hard composite to deliver a firmer rear hub that improves corner entry and mid corner stability. It helps preserve suspension geometry under load, which leads to more predictable handling during race runs. This upright is compatible with RX8E 2023 models and is aimed at competitive drivers.

Consistency and Handling Precision

The hard composite XRAY 343311-H reduces unwanted movement in the rear end, keeping toe and camber settings consistent between heats. That consistency makes it easier to fine tune the car and trust setup changes. The uprights are a useful upgrade for drivers who value repeatable results.

When to Fit This Upright

Fit this part if you notice inconsistent rear behaviour or if you are moving to a stiffer overall setup. Its stability helps when running higher downforce or stiffer anti-roll bars, letting you extract more lap time from precise adjustments. The XRAY 343311-H is a reliable option for competition builds.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Does this replace the stock upright directly?

Yes, it is a direct replacement for RX8E 2023 upright locations and mounting pattern, so no custom machining is required.

What are the main benefits on race day?

Expect reduced setup drift and clearer steering feedback, which makes tyre and damping choices easier to optimise during an event.

Are there any compatibility notes with upgrades?

It works well alongside stiffer suspension components and aluminium uprights, but confirm link lengths and ball stud positions when mixing different parts.

How do I check for wear?

Inspect mounting holes and bearing seats after crashes; any elongation or cracking warrants replacement to keep geometry accurate.

Will it change suspension feel significantly?

You will notice a firmer rear feel and crisper responses. Adjust shocks and anti roll bars as needed to regain the preferred balance.
