XRAY 301063 - T4'21 1.6mm Graphite Upper Deck for Race Stability  [XR-301063]

Fine tune your T4'21 with the XRAY 301063 graphite top deck

The XRAY 301063 graphite upper deck, cut to 1.6mm, is specified for the T4'21 to refine handling on low to medium grip circuits. It provides a controlled change to chassis flex that racers can use to gain steadier steering and improved mid corner grip.

Balanced design to complement the aluminium chassis

The 1.6mm graphite panel is intended to work in concert with the T4'21 aluminium chassis, modifying steering input and stability without radical setup changes. This makes it straightforward to test during race weekends.

Three mounting modes for precise setup tuning

The XRAY 301063 lets you select between mount options to alter flex characteristics according to conditions and driver preference:

• Soft Setting: Omitting the deck-to-stand connection increases lateral flex for more front end steering, but can demand smoother throttle control.
• Medium Setting: A ball-bearing connection provides lateral compliance while keeping front-to-rear stiffness for predictable balance.
• Stiff Setting: A fixed bushing reduces deck movement and promotes stability through fast corners.
