XRAY 301070 X4 Graphite Upper Deck - Precision Flex Plate  [XR-301070]

Why Fit the XRAY 301070 Upper Deck

The XRAY 301070 X4 Graphite Upper Deck is a lightweight 2.0mm graphite plate that helps refine the balance between traction and steering response. Its engineered layout gives racers clear options to alter chassis flex for changing conditions.

Four Flex Choices Explained

This upper deck offers four distinct flex configurations to tune how the car turns and how stable it feels on power. Choose a mode that matches your setup and surface:

• Soft Setting: No bushings or bearings create maximum flex and sharper initial steering, though it can feel less planted under full throttle.
• Soft-Medium Setting: Installing a ball bearing to the motor mount eases oversteer and improves mid-corner composure.
• Medium Setting: The M3x5.5mm screw behind the layshaft produces a compromise between agility and straight-line control.
• Stiff Setting: Using screws both behind and ahead of the layshaft stiffens the chassis for stable exits and more precise steering inputs.
