Upgrade rear-end control on your RX8.3 with XRAY 343713

The XRAY 343713 Aluminum Rear Lower Suspension Holder is a precision part that strengthens rear support on the RX8.3 chassis. Manufactured from Swiss 7075 T6 aluminum, it offers a durable yet lightweight replacement to stock components.

Improved Rear Traction

Mounted at the front of the rear bulkhead, the holder narrows the rear lower arm spacing by 2.5mm to increase traction and reduce rear looseness. This change gives more predictable corner exits and steadier high speed behaviour.

Designed for Tuning and Reliability

With CNC accuracy, the holder provides repeatable fitment for tuning sessions and upgrades. It is suitable for drivers who want consistent handling improvements without major chassis surgery.

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 XRAY 343713 reduce chassis flex?

Yes. Replacing softer materials with 7075 T6 aluminum reduces flex in the rear bulkhead area, which can sharpen handling response.

Should I re-check suspension geometry after fitting?

Absolutely. After installing the holder, verify rear arm alignment, toe and camber to ensure the car tracks as expected.

Is the part compatible with older RX8 variants?

This holder is specified for the RX8.3 chassis. Compatibility with older RX8 versions is not guaranteed without verifying mounting points.

What maintenance does this aluminium holder need?

Inspect mounting screws for loosening and check for wear or burrs. Clean and lightly lubricate mating surfaces during regular maintenance.
