XRay X4F25 Graphite Upper Deck 2.0mm

The XRay X4F25 Graphite Upper Deck 2.0mm (XR301085) is a one-piece carbon Multi-Flex™ top deck with a narrow profile for easier installation and refined on-track response. It delivers increased flex compared with a two-piece layout, softening the car’s feel and enhancing mechanical traction on low-traction surfaces while slightly calming initial steering.

With eight different flex adjustment alternatives, you can dial in the balance to suit track conditions. The deck can also be further customised with additional cuts to unlock even more flex set-up options. Precision, tweak-free mounting helps maintain consistent flex behaviour, and the shape is engineered to maximise traction without sacrificing confident steering. CNC-machined from premium, high-grade carbon fibre made in the USA.
