ARC A11 Front Split Upper Deck for Chassis Tuning, Graphite 1.6mm - O-ARCP05S by Factory Pro  [FP-O-ARCP05S]

ARC A11 front split upper deck overview

This split upper deck is a front chassis piece made for the ARC A11 platform. Constructed from 1.6mm graphite, it reduces front compliance to sharpen steering feedback and support fine tuning of corner entry characteristics.

The part bolts into the ARC A11 upper-deck mounting points without changing the stock geometry. Install with correct alignment and even screw torque to preserve symmetry and avoid distortion. Confirm fitment with surrounding components before final assembly.

As a tuning change, moving to a thinner, split graphite deck like this typically tightens turn-in and increases front-end feel; introduce changes one at a time and use lap testing to evaluate the overall balance.
