XRAY 301061 T4'20 1.6mm Graphite Upper Deck Setup Kit  [XR-301061]

Tuning guide for the XRAY T4'20 upper deck

The XRAY 301061 T4'20 Graphite Upper Deck is manufactured to give drivers precise control over chassis flex. At 1.6mm thickness the graphite plate is a light, stiff option that complements aluminium chassis layouts on lower to medium grip circuits.

What each flex setting does

The deck is symmetrical for consistent performance left to right. Use these linking choices to alter handling behaviour:

• Soft Setting: Leave the deck unmounted to the stand to allow the most lateral movement and quicker steering reaction, useful for twisty sections.
• Medium Setting: Fit a ball-bearing link so the deck can pivot side to side while keeping lengthwise stiffness, producing a balanced feel for mixed layouts.
• Stiff Setting: Secure with a fixed bushing to eliminate flex and improve stability at higher speeds or on smoother surfaces.

Track and chassis pairing

This deck is best used with an aluminium chassis on tracks where traction is limited to moderate. Graphite gives the needed stiffness without heavy weight penalties.
