The 3RACING Auper D6 Red Aluminum Upper Deck SAK-D6811/RE replaces the factory plate with a tougher aluminium option to cut flex and improve stability. It is aimed at drivers who want cleaner handling through fast sections.
Compared with stock plastic, this red aluminium part increases structural rigidity and helps control chassis twist when pushing hard. That stiffness makes suspension behaviour more repeatable lap after lap.
Drivers focused on lap time or precise cornering will notice crisper inputs and reduced chassis movement. The 3RACING SAK-D6811/RE suits tuning setups where minimizing flex is a priority.
