XRAY 301063 T4'21 1.6mm Graphite Upper Deck - Precision Handling Upgrade  [XR-301063]

Dial in traction on the T4'21 with the XRAY 301063

The XRAY 301063 Graphite Upper Deck for the T4'21 is a precision 1.6mm top deck engineered to refine handling on low to medium grip surfaces. Made to help racers tune steering feel and mid corner traction, it works with the chassis to deliver predictable control.

Engineered flex to improve cornering balance

This 1.6mm graphite upper deck pairs with the T4'21 aluminum chassis to adjust front end bite and overall steering response. Its profile is intended to increase mid corner grip while maintaining stability on entry and exit.

Three mount choices let you set the flex you need

The XRAY 301063 offers multiple mounting options so you can tailor chassis flex to your driving style:

• Soft Setting: Leaving the deck unconnected to the stand gives maximum lateral flex for increased steering, though it requires smoother inputs to control.
• Medium Setting: Using a ball-bearing connection allows sideways flex while keeping front to rear stiffness, offering a balanced setup for many tracks.
• Stiff Setting: A fixed bushing connection reduces flex, increasing stability and predictability at higher cornering loads.
