The 3Racing SAK-D627 rear bulkhead lower stiffener is a straightforward reinforcement for the Sakura D6 Sport chassis. It helps control rear chassis movement under load, promoting steadier lines and more consistent behaviour through a sequence of turns.
By reducing rear flex the stiffener allows the suspension to operate with greater predictability, which can improve mid corner traction and exit stability. This makes setup changes more effective and easier to tune at the track.
Engineered for Sakura D6 compatibility, the part installs using the vehicle's standard fixing points. The upgrade is aimed at drivers who want a reliable, no-fuss way to refine chassis balance without extensive modification.
