If you want to tune an XRAY T4-16, the RADTEC RAD-XR-10026 Graphite Main Chassis is a practical upgrade. Built in the USA, the 2.25mm graphite construction is aimed at vintage XRAY T models and balances lightweight feel with solid structural support.
The RADTEC plate improves responsiveness and corner stability on the XRAY T4-16. The 2.25mm thickness provides measured flex to absorb track irregularities while retaining enough stiffness to keep the car stable at speed, helping drivers maintain predictable lines.
This chassis is made for older XRAY T configurations and installs without extensive changes, making it suitable for restorations and performance swaps. It adapts well to different electronics layouts and driving styles to suit various surfaces.
