This carbon upper deck is an RC-scale replacement part for the X4F 27 chassis, designed to let drivers tune chassis flex and rotation. The split rear layout and narrow profile ease installation while permitting a range of flex settings by changing top deck mounting screws.
The deck is CNC-machined from premium high-grade carbon fiber made in the USA and supplied with 2 pcs mounting screws for the rear section to increase flex where needed. The Multi-Flex concept uses screw positions to vary stiffness, impacting traction and steering balance without altering other suspension components.
Install notes: the narrow shape clears nearby components for straightforward fitment on X4F 27 layouts, and the split rear lets you focus flex changes toward the back end to influence rotation and rear bite during corner exit.
For builders wanting precise chassis tuning on X4F 27 cars, this deck provides a simple way to adjust rear flex and rotation through mounting choices while maintaining a lightweight, CNC-finished carbon construction.
