ARC A11 Rear Body Plate Soft Graphite by Factory Pro O-ARCP14S  [FP-O-ARCP14S]

ARC A11 rear body plate — soft graphite

This Factory Pro aftermarket rear body plate is made for the ARC A11 chassis and uses a softer graphite layup to alter rear-end flex characteristics on RC touring car setups. As an RC-scale spare part, it focuses on fine-tuning chassis balance and traction response rather than providing major structural changes.

Design intent: the soft graphite material reduces local stiffness at the rear mounting area, which can slightly increase rear grip and make the car more compliant over mid-speed bumps. This is intended for drivers who tune through incremental changes to rear flex to affect oversteer/understeer balance.

Installation notes: the plate is produced to suit ARC A11 mounting points and replaces the stock rear body plate without requiring chassis modification. Standard fasteners from the ARC A11 chassis are used for mounting; confirm thread engagement and torque to match your usual setup practice.

Tuning guidance: use this plate as one element in a broader setup approach—combine with suspension, shock, and tyre adjustments. Expect subtle changes; evaluate on-track through controlled test runs and change only one item at a time to isolate effects.
