TAMIYA F103GT Rear Top Deck Graphite Upgrade F103GT-12/SG by 3Racing  [F103GT-12/SG]

Rear top deck upgrade for F103GT

This graphite rear upper deck is an aftermarket hop-up for the TAMIYA F103GT chassis supplied under part code F103GT-12/SG. It is built to the SSG rear-deck mounting pattern so it replaces the stock plate with a stiffer graphite element that influences chassis roll and traction behaviour on 1/10 GT setups.

Installation is simple for anyone used to F103 maintenance: remove the original rear plate, align the graphite unit to the same locating points, and refit the factory screws. After fitting, check clearance around the motor mount and the rear suspension throughout its travel. No permanent chassis modification is necessary for standard F103GT frames.

On-track the upgrade reduces rear-end compliance which helps with more consistent corner exits and more direct throttle response. Combine this change with measured adjustments to damping or anti-roll bars when refining the car's balance.

Ideal for drivers chasing repeatable handling, fit this plate then tune suspension incrementally to suit your driving style.
