XRAY 301063 T4'21 1.6mm Graphite Upper Deck - Race Control Edition  [XR-301063]

Get sharper steering on the T4'21 with the XRAY 301063

The XRAY 301063 Graphite Upper Deck, made as a 1.6mm top deck for the T4'21, helps fine tune steering feel and traction on lower grip surfaces. It is intended for racers who want a controllable increase in responsiveness without overhauling the chassis.

Designed to work with the aluminium chassis for balanced grip

The 1.6mm graphite panel works alongside the T4'21 aluminium chassis to influence front bite and mid corner stability. Its construction aims to give predictable changes to handling so you can adjust setup with confidence.

Set your flex - soft, medium, or stiff

The XRAY 301063 features multiple mounting choices so you can alter flex to suit track conditions and driving style:

• Soft Setting: Leaving the deck unmounted to the stand increases lateral flex for added steering, which can be lively to drive.
• Medium Setting: A ball-bearing link allows controlled sideways flex while preserving longitudinal rigidity, a versatile option on many circuits.
• Stiff Setting: Use a fixed bushing connection to lock down flex for consistent stability through fast sections.
