Xray X4'26 Rear Upper Deck Graphite 1.6 - Factory Pro O-XCP032S  [FP-O-XCP032S]

Factory Pro O-XCP032S rear upper deck for Xray X4'26 - graphite 1.6 as a targeted chassis component

The Factory Pro O-XCP032S is a dedicated rear upper deck made for the Xray X4'26 chassis, CNC machined from graphite to a nominal 1.6 mm thickness. It is a direct-fit structural plate intended to shift local chassis stiffness and keep suspension pick-up points aligned under load. Fitted at the same location as the stock upper deck, it influences how the rear bulkhead ties into the centre bracing and how torsion is transferred across the rear section.

Why 1.6 mm graphite matters

At 1.6 mm the graphite offers a compromise between rigidity and controlled flex, sitting between very thin carbon options and much stiffer composite plates. In practice this provides measurable contribution to both longitudinal and lateral stiffness while remaining tolerant of minor impacts. The hole pattern and machining follow the X4'26 layout so repeatable mounting and alignment are preserved during rebuilds or part swaps.

Fitment and chassis role

This plate is designed specifically for the Xray X4'26 and replaces the factory rear upper deck using the original mounting points. As an aftermarket structural item it alters the rear section behaviour that affects traction transition and roll centre characteristics by changing how the rear bulkhead connects to the centre bracing.

Who will use this part

Hobbyists and builders maintaining or restoring Xray X4'26 touring cars will find the FP O-XCP032S useful when seeking a dimensionally accurate graphite replacement. It suits those focused on consistent chassis assembly, repeatable geometry, or collectors who want an alternative material while keeping original fitment characteristics.

Practical selection notes

Treat this plate as a targeted structural tweak: its effect is concentrated on stiffness distribution and assembly repeatability rather than a catch-all handling fix. It retains the original mounting architecture, so check fastener condition and confirm hole alignment before installation.

As a focused aftermarket component, the Factory Pro O-XCP032S supplies a dimensionally accurate graphite rear upper deck for the Xray X4'26, providing a reliable option for builders chasing consistent chassis behaviour and a different material feel.
