Xray X4'26 Upper Deck Graphite 1.6 Medium Stiffness - Factory Pro FP-O-XCP031S  [FP-O-XCP031S]

Factory Pro FP-O-XCP031S 1.6mm graphite upper deck for Xray X4'26 touring cars

Effect on chassis stiffness and dynamics

The FP-O-XCP031S upper deck is a drop-in replacement made for the Xray X4'26 platform. As a medium-stiff 1.6mm graphite plate it locates between bulkheads and the top components to manage local flex and distribute loads across the centre section. In use the deck modifies how front and rear modules interact through the centre, making it a practical choice for tuners who want mid-chassis stiffness changes without altering suspension geometry.

Construction and material advantages

Graphite is widely used for upper decks because of its stiffness-to-weight ratio. The 1.6mm thickness chosen for the FP-O-XCP031S delivers a compromise between rigidity and some compliance. The plate shape, including cutouts and mounting bosses, determines how it couples with shock towers and bulkheads. The result is a lightweight, resilient part that stands up to regular hobby use.

Fitment and intended use

Specifically designed for the Xray X4'26, the FP-O-XCP031S matches factory interface points for a direct replacement on the same chassis generation. Its effect is concentrated on the centre structure and is most relevant for restorers and tuners reviewing chassis feel or aiming for a period-correct setup.

Ideal user profile

The deck is ideal for enthusiasts who run Xray X4'26 cars and want a dependable graphite replacement that subtly changes mid-chassis rigidity. It is suitable for maintenance, restoration, and incremental tuning where owners prefer genuine-style components rather than major platform changes.

Factory Pro FP-O-XCP031S is a sensible mid-stiffness upper deck for Xray X4'26 owners seeking a durable graphite replacement that adjusts centre stiffness without deeper platform modifications.
