The 3Racing Sakura D4 Aluminum Bulkhead is a precision replacement part for the Sakura D4 platform. CNC style manufacturing and a rigid aluminum construction tighten critical mounting points and reduce deformation under lateral and longitudinal loads.
By limiting chassis flex at the front mount, the bulkhead preserves suspension geometry and improves repeatability between runs. That stability simplifies setup work, allowing incremental changes to toe, camber and roll centre without unpredictable chassis variables.
For tuners and racers, the 3Racing bulkhead provides a firmer foundation for setup development and delivers consistent handling across multiple track sessions.
