For racers wanting firmer control, the Factory Pro O-ARCP02 Graphite Upper Deck fits the ARC A10MF'24 precisely and raises torsional stiffness. Made from 2mm graphite, it reduces unwanted flex while keeping the overall mass low for quicker steering response.
Swapping the stock upper deck for this graphite part tightens the chassis feel and helps maintain consistent balance through high speed corners, which is useful for lap time gains on paved tracks.
The 2mm graphite construction delivers a stiff platform without adding noticeable weight, preserving acceleration and top speed while supporting fine suspension setups.
