3Racing Sakura M4 Aluminum Bulkhead SAK-M4S45 - Racing Setup Part  [SAK-M4S45]

3Racing SAK-M4S45 Bulkhead for Precision Setup

Engineered for the Sakura M4, the 3Racing Aluminum Bulkhead (SAK-M4S45) provides a rigid mounting platform that reduces chassis deflection and preserves alignment under load. It is designed to make suspension adjustments more predictable for lap time improvements.

Track-Focused Construction

The aluminium construction increases torsional stiffness at the front end, which helps maintain steering geometry during heavy braking and high lateral loads. This promotes consistent handling and simplifies corner entry tuning.

Tuning and Reliability

As a direct replacement for stock parts, the 3Racing SAK-M4S45 supports higher cornering forces and repeated setup cycles without significant deformation. That reliability makes it a practical performance upgrade for competitive drivers focused on setup refinement.
