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

ARC A11 Upper Deck — 2mm Graphite Fit

This 2mm graphite upper deck is intended for the ARC A11 chassis as a precision aftermarket part. It replaces the standard deck to alter chassis stiffness and tuning feel while keeping suspension geometry intact.

Installation: the plate secures to the original ARC A11 attachment points and uses the existing fasteners. Before fitting, check screw lengths and component clearances to avoid interference. Extra parts are not normally required.

Performance note: increasing the deck stiffness modifies mid-span flex, usually sharpening initial turn-in and reducing roll under acceleration. These handling changes can affect traction; incorporate the deck as part of a step-by-step setup process to quantify its impact on lap times and tyre wear.

This graphite upper deck is a direct replacement designed for ARC A11 hobbyists who want a predictable change in chassis flex to fine tune handling across varied track surfaces.
