ARC A11 Upper Deck Brace 1.6mm Graphite for Chassis Tuning - O-ARCP08 by Factory Pro  [FP-O-ARCP08]

Reinforced upper deck for ARC A11 handling

The Factory Pro O-ARCP08 is an aftermarket upper deck brace designed for the ARC A11 chassis. Made from 1.6mm graphite, this brace increases upper-deck stiffness to give clearer feedback from the chassis during tuning and setup.

The brace is intended for RC-scale use and matches the ARC A11 upper deck mounting pattern. Installed in place of or alongside the stock brace, it alters how the chassis distributes load under acceleration, braking and cornering, helping drivers dial in roll center and mid-corner grip without changing suspension geometry.

Installation notes: the part uses the A11’s existing upper-deck attachment points, so standard mounting screws are normally retained; check fit and clearances with electronics and body before final tightening. When tuning, expect small but measurable changes in steering responsiveness and chassis balance, useful for track tuning or practice sessions.
