For ARC A11 Rear Upper Deck Upgrade 2mm Graphite Plate - O-ARCP06 by Factory Pro  [FP-O-ARCP06]

Split Rear Deck Overview

This is an aftermarket split upper deck rear crafted for the ARC A11 chassis and sold as Factory Pro O-ARCP06. The component is a 2mm graphite plate made to replace the standard rear upper deck while preserving the split configuration used on the original ARC A11.

Functionally, the rear upper deck controls local torsional stiffness behind the radio tray and impacts rear-end behaviour during cornering. Fitting the graphite plate provides an alternative stiffness profile that racers use to tune mid to high speed rear traction and general chassis balance without modifying suspension geometry.

The installation process is straightforward for experienced model builders: remove the factory rear upper deck, move any required mounts or spacers to the new plate, align the split pieces and fasten using the OEM screws. Always check clearance around the motor, servo and radio tray before completing installation.

Tuning guidance: raising rear deck stiffness usually reduces rear roll and can help traction transition at corner exit, while a more flexible deck can assist grip on low traction surfaces. Make small changes and run tests to judge handling impact; this plate is one option in a broader setup plan.
