The Factory Pro O-XCP030S front upper deck is a dedicated graphite plate made to fit the Xray X4'26 touring car platform. As a direct-fit replacement, the 1.6 mm graphite piece is intended to increase front-end stiffness while keeping the mounting geometry that defines the X4'26 chassis layout. Consider this part a chassis stiffness adjustment rather than a cosmetic change.
Graphite is selected where added stiffness with low weight change is desired. At 1.6 mm thickness this deck raises front torsional resistance in a measured way. The machined hole pattern matches X4'26 reference points so torque paths and connection points behave predictably for racers tracking setup changes.
The front upper deck is produced to align with Xray X4'26 mounting features. Standard screw and spacer positions are preserved, maintaining upper link points and shock tower alignment. That makes it straightforward to swap in without altering the basic front geometry.
O-XCP030S appeals to experienced builders and tuners who modify components on an established platform. It is also useful for restorers replacing an original plastic deck with a more consistent graphite part to retain chassis behavior over time.
On the X4'26 the front upper deck ties multiple structural nodes together. Moving to a 1.6 mm graphite plate shifts how loads transfer between the front bulkhead and shock towers, subtly changing stiffness distribution. This is a mechanical change only and does not affect electronics or drivetrain layout.
The O-XCP030S front upper deck is a focused graphite option for Xray X4'26 owners seeking consistent, repeatable front-end stiffness without changing mounting geometry.
