The 3Racing SAK-D131/FRP FRP Upper Deck is a targeted reinforcement for the Sakura D3 CS SPORT chassis, constructed from fibre reinforced plastic to improve chassis cohesion. This part reduces unwanted flex to create a firmer platform for suspension tuning and more predictable lap to lap behaviour.
Fitting the FRP upper deck results in clearer steering input and steadier behaviour through mid corner transitions. The FRP material adds strength without a heavy penalty, so the car retains agility while gaining structural consistency.
The deck is produced to match Sakura D3 CS SPORT mounting points for a direct fit. Hobbyists can install the 3Racing SAK-D131/FRP with common hand tools and should notice improved turn-in and chassis response immediately after fitting.
