The Factory Pro O-XCP010 upper deck is a direct-replacement graphite plate designed for Xray X4 chassis upkeep and detailed setup work. As a structural hop-up it mounts between the main bulkheads and alters the route of loads across the radio tray and suspension towers.
This component functions as a tuning element rather than an instant performance booster: fitting Graphite 2.0 alters chassis stiffness and will influence mid-corner stability, steering precision and how the suspension shares loads. Use it alongside shock and anti-roll adjustments when refining handling.
Installation is simple for experienced operators: remove the existing top deck, line up the mounting points with the chassis bulkheads and secure with the car's original fasteners. Check servo link clearance and radio tray fit after fitting. No additional parts or tools are supplied.
Fit this Graphite 2.0 upper deck when you want a controlled rise in top-end rigidity as part of iterative tuning on Xray X4 cars.
