This RC-scale rear body plate is designed for the ARC A11 chassis and supplied as an aftermarket replacement by Factory Pro. Made from graphite, the plate provides a stiffer mounting surface for the rear section of the body shell while remaining lightweight. The part is intended for hobbyists who want a predictable change to rear-end response and a stable basis for suspension and body setup work.
Installation follows the existing ARC A11 body mounting points and replaces the stock rear body plate without requiring chassis modifications in typical fits. Check alignment and screw torque during installation, and verify body clearance through the suspension travel to avoid rubbing. The plate's role is primarily tuning-focused: it alters how the rear shell distributes load and can influence transient grip and rotation characteristics at the rear of the car.
Because this is an RC-scale accessory, use it only on compatible ARC A11 models and in RC workshop settings; do not apply to full-size vehicles.
