Factory Pro O-XCP032S graphite rear upper deck for Xray X4'26 - precision chassis piece
The Factory Pro O-XCP032S is an aftermarket rear upper deck made for the Xray X4'26, cut from graphite to a nominal 1.6 mm thickness. It is a direct-fit structural plate intended to modify the stiffness profile of the rear section while maintaining suspension pick-up alignment. Positioned where the stock upper deck controls torsion and rear bulkhead tie-in, it is selected by builders seeking precise chassis feel.
Graphite at 1.6 mm and its role
Graphite of this thickness strikes a balance between rigidity and controlled flex, offering more control than very thin plates without the brittleness of heavy composites. That translates to improved longitudinal and lateral stiffness in targeted areas while remaining serviceable after routine club use. Machining adheres to X4'26 geometry, preserving mounting accuracy and repeatability.
Fitment details
Specifically engineered for the Xray X4'26, the O-XCP032S replaces the factory rear upper deck and uses existing mounting points. As an aftermarket structural plate it changes the way the rear bulkhead ties into centre bracing, which can influence rear traction transition and roll centre behaviour.
Who should consider this upgrade
This part is for racers and enthusiasts who maintain or restore Xray X4'26 cars and want a dimensionally accurate graphite option. It is suitable for those chasing consistent assembly and repeatable geometry rather than a universal handling cure.
Usage notes
Consider the plate as a specific tuning element: its primary effect is on stiffness distribution and repeatability. Confirm the condition of existing fasteners and mating surfaces during installation and combine it with suspension tuning for best results.
