The 3Racing SAK-D626 is engineered to reinforce rear mounting points on the Sakura D6, reducing compliance that can alter geometry under load. This upgrade helps maintain intended roll centre and pivot alignment for more repeatable handling across variable track surfaces.
By firming up the connection between the upper linkage and deck, the 3Racing SAK-D626 minimises transient deflection so corner entry and exit behaviour become more linear. Tuners will note that setup changes produce more predictable results with reduced chassis variance.
Fit the 3Racing SAK-D626 with correct fastener torque and verify concentricity of pivot points after assembly. Periodic inspection for thread integrity and mounting hole wear is advised when used in intense racing environments.
