This specially made upper deck is constructed from flexible and durable glass fiber material, which increases the flex of the car and improves handling on low- to medium-grip tracks.

Specifications:

• Material: 1.5mm glass fiber
• Designed for maximum traction and great steering characteristics

Connection Options:

• Soft Setting: Only one rear screw is used. This allows maximum flex and provides maximum steering. However, the car is less stable on power.
• Stiff Setting: Both screws are used. This setting reduces flex both in front and rear, decreases mid-corner steering, and rotation. It provides maximum stability and makes the car easier to drive.
