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

Graphite rear top deck for F103GT

This graphite rear upper deck plate is an RC hop-up made for the TAMIYA F103GT platform and supplied as part code F103GT-12/SG. The plate is a direct-replacement style component that matches the stock SSG rear mounting layout, using graphite to raise chassis stiffness and sharpen handling feedback on 1/10 scale GT cars.

Fitting is straightforward for technicians familiar with the F103 series: remove the factory rear deck, locate the graphite plate to the same mounting points, and secure with the original fasteners. After installation check clearance around the motor pod and rear suspension travel. No drive-train alterations are required when installed on compatible F103GT layouts.

Tuning impact on track is predictable: a stiffer rear deck reduces flex at the back of the chassis which tends to stabilise corner exit and make weight transfer easier to manage. Use this upgrade alongside measured changes to damping and anti-roll settings to refine balance between understeer and oversteer.

Fit this plate when you want a firmer rear end for repeatable lap times, and tune suspension progressively to find the best mid-corner and exit behaviour.
