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

Upper Deck for ARC A11 — Graphite 2mm

A 2mm graphite upper deck manufactured for the ARC A11 platform, supplied as a replacement part to alter chassis stiffness and handling response without changing suspension geometry.

Assembly guidance: the deck mounts to the ARC A11's existing upper deck points using the same fastener locations. Check current screw lengths and surrounding components for clearance prior to final assembly. Additional components are typically not necessary.

Tuning advice: the stiffer deck shifts mid-span flex behavior, which often tightens turn-in and improves mid-corner stability while potentially reducing some mechanical grip. Introduce the part as a single variable and run controlled tests to judge lap time and tyre wear impacts.

This graphite upper deck is a direct-fit option for ARC A11 enthusiasts seeking a deliberate stiffness change to tune handling for various circuit conditions.
