XRAY 301072 X4 2.0mm Split Front Graphite Upper Deck  [XR-301072]

Precision Steering Upgrade for XRAY X4 301072

The XRAY X4 Graphite Upper Deck - Split Front 2.0mm provides a practical way to refine steering feel and chassis response on asphalt circuits. Its split arrangement lets racers target front-end flex without changing the whole chassis layout.

Material Choice and Structure

Forged from 2.0mm graphite, this split upper deck is designed to influence traction and steering accuracy. The dual-piece design separates front and rear behaviour so tuners can alter flex across different racing surfaces.

Two-Position Flex Adjustment

Use the split layout to select from two configurations:

• Soft Setting: Fastening only the rear screw increases flex and sharpens turn-in, which helps on tighter asphalt sections but can reduce stability when accelerating hard.
• Stiff Setting: Fastening both screws limits flex for a steadier, more predictable car at higher speeds and on smoother tracks.
