ARC A11 Upper Deck Stiffener 1.6mm Graphite Upgrade for ARC A11 - O-ARCP08 by Factory Pro  [FP-O-ARCP08]

Upper deck stiffener tuned for ARC A11 setup

The Factory Pro O-ARCP08 is an aftermarket upper deck brace crafted for the ARC A11 chassis. Using 1.6mm graphite, the unit increases upper-deck stiffness so drivers receive crisper feedback when dialing in handling.

Made for RC-scale competition, the brace fits the ARC A11 upper deck mounting pattern. Fitted in place of or with the stock component, it changes how the chassis transfers load under acceleration, braking and cornering to assist tuning roll center and mid-corner behavior without altering suspension geometry.

Installation guidance: the brace uses the existing A11 upper-deck attachment points so you can usually reuse standard mounting screws; confirm clearance around electronics and the body before final torque. When testing, anticipate subtle but measurable shifts in steering response and balance useful for track tuning.
