ARC A11 Split Upper Deck Lite Front - Graphite 1.6mm by Factory Pro O-ARCP05S  [FP-O-ARCP05S]

Front split upper deck for ARC A11

This split upper deck is an RC-scale front chassis component produced for the ARC A11 platform, offering a lightweight graphite construction at 1.6mm thickness designed to influence front-end stiffness and tuning response. It is intended for hobbyists who adjust chassis flex to refine steering feedback and corner entry behavior on track setups.

The part mounts to the factory upper-deck points on the ARC A11 without altering mounting geometry, so installation focuses on correct alignment and even screw torque to maintain symmetry. Because this is a scale accessory, verify fit and clearance with existing components before final assembly.

In tuning terms, substituting the standard upper deck with a thinner graphite split deck like this one typically reduces overall front compliance, which can tighten turn-in and increase front-end feel; use incremental changes and lap testing to evaluate effects on balance rather than making multiple changes at once.
