The 3Racing SAK-D120/PK solid axle provides a stable rear reference for the Sakura D3 CS SPORT chassis, useful when refining suspension and differential settings. Its design aims to reduce rear-end variability so tuners can focus on fine adjustments.
When fitting the SAK-D120/PK, assess rear roll behaviour, toe settings and shock valving as a cohesive package. The axle changes how weight shifts during transitions, so incremental setup changes are recommended for consistent results.
