The 3Racing SAK-D644GA/PU is a carbon graphite rear body post plate produced to interface with the Sakura D6 chassis. It is engineered to reduce weight at the rear body mount while increasing local stiffness for predictable rear-end behaviour during aggressive driving.
Carbon graphite provides a high stiffness to mass ratio, improving chassis feedback and limiting unwanted flex at the mounting points. This aids setup work by making changes to suspension and trim more repeatable on lap after lap.
Designed to the Sakura D6 mounting layout, the plate installs without modification and secures the rear shell consistently. The purple finish is cosmetic but the component is intended first for function in competitive or club racing setups.
