Precision rear suspension upgrade for RX8.3 with XRAY 343713

The XRAY 343713 Aluminum Rear Lower Suspension Holder is a carefully engineered upgrade that improves handling and chassis balance on the RX8.3. Machined from Swiss 7075 T6 aluminum, the holder delivers a strong yet light solution to maintain responsiveness on the track.

Installed at the front of the rear bulkhead, this holder shifts the rear lower arms 2.5mm closer together to increase traction and create a more stable rear end. The result is smoother cornering and more predictable behaviour during high speed runs.

Setup-Friendly Upgrade and Fitment

Ideal for drivers refining their setup, the precision CNC construction ensures consistent fitment for tuning or replacement. The design suits both competition setups and weekend practice rigs where dependable performance matters.

A straightforward upgrade for hobbyists and racers wanting a firmer, more controlled rear end on the RX8.3.

Yes. The holder is made to mount to the front of the RX8.3 rear bulkhead and matches the OEM mounting points for direct installation.
No. The holder repositions the lower arms by 2.5mm without requiring new arms, but you may want to recheck toe and camber after fitting.
7075 T6 offers a strong, lightweight option compared with plastic parts, improving durability and reducing flex for sharper handling.
Tighten hardware to spec and verify arm alignment. After fitting, run a few test laps to fine tune shock and anti-squat for the new rear balance.
