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

Overview — Split Upper Deck Rear

This split upper deck rear is an aftermarket replacement formed for the ARC A11 chassis and supplied under the designation Factory Pro O-ARCP06. The component is a 2mm graphite plate intended to replace the rear upper deck while retaining the split arrangement found on the original ARC A11 assembly.

From a handling perspective, the rear upper deck controls local torsional stiffness behind the radio tray and influences rear-end response during cornering. Changing to this graphite plate alters the stiffness profile so drivers can adjust mid to high speed traction and overall chassis balance without altering suspension geometry.

Installation is simple for those with assembly experience: remove the original rear upper deck, transfer any mounting hardware or spacers, align the split panels and fasten with the original screws. Check clearance to the motor, servo and radio tray before completing assembly.

Tuning advice: a stiffer deck often reduces rear roll and can smooth traction transition on corner exit; a more forgiving deck may improve grip on low traction circuits. Make measured changes and evaluate through timed runs; this plate complements other setup modifications.
