TAMIYA F103GT SSG Graphite Rear Upper Deck Plate by 3Racing F103GT-12/SG  [F103GT-12/SG]

Rear upper deck plate for F103GT

This graphite rear upper deck plate is an RC-scale hop-up designed around the Tamiya F103GT platform and supplied under 3Racing part code F103GT-12/SG. The component is a direct replacement style part intended to match the mounting layout of the original SSG plate, using graphite as the structural material to influence chassis stiffness and handling feedback in 1/10 scale GT setups.

Installation is straightforward for shops familiar with F103-series maintenance: remove the factory rear deck, align the graphite plate to the same locating points, and secure with the original mounting screws. As with any rigid deck upgrade, confirm clearance for the motor pod and rear suspension movement after fitting. No additional modifications to drive components are required when used on compatible F103GT chassis.

On-track tuning role: swapping the stock plate for a graphite upper deck reduces flex at the rear of the chassis, which tends to stabilise corner exit and make weight transfer more predictable. This change is useful when seeking crisper response under throttle or when balancing understeer and oversteer with other setup items such as shock damping and anti-roll adjustments.

Use this plate where a firmer rear end is needed for consistent lap-to-lap behaviour, and pair it with incremental suspension adjustments to dial the desired balance.
