XRAY 301090 X4'26 Glass Fibre Upper Deck for Tunable Flex  [XR-301090]

Better Balance with XRAY Glass Fibre Upper Deck

Run with improved balance using the XRAY 301090 X4'26 glass fibre upper deck, engineered to add controlled flex for varied surface grip. Constructed from 1.5mm glass fibre, the component enhances tyre bite and turn-in precision. The design makes it simple to adapt the chassis feel to suit different track layouts and driving approaches.

Two Position Flex Control

The upper deck provides two clear flex choices:

• Soft Setting: Leave only the rear inner screw installed to increase chassis flex and boost steering response. Great for tight circuits where agility matters, but note it can reduce stability under acceleration.
• Stiff Setting: Install both rear screws to stiffen the assembly, improving straight-line composure and easing car control. This setting reduces over-rotation and helps with consistent corner exit.
