ARC A11 Upper Deck Graphite 2mm - O-ARCP04 by Factory Pro  [FP-O-ARCP04]

ARC A11 Graphite Upper Deck (2mm)

This 2mm graphite upper deck is made for the ARC A11 chassis as a precision spare part. It replaces the factory plate to increase mid-span stiffness and refine tuning response while leaving suspension geometry unchanged.

Installation notes: fitting is straightforward for those familiar with ARC A11 maintenance. The deck mounts to the original upper deck locations and uses the same fastener positions, so confirm screw lengths and clearances before final assembly. No additional components beyond the vehicle's original hardware are required.

On-track tuning overview: a firmer upper deck changes mid-span flex, generally sharpening turn-in and reducing chassis roll under power which influences traction and steering balance. Apply this upgrade incrementally and test one setup variable at a time to measure lap time and tyre wear effects.

As a direct replacement upper deck, this graphite plate suits ARC A11 users wanting a predictable change in chassis stiffness for controlled setup tuning across different track surfaces.
