3Racing Sakura M4 Aluminium Bulkhead SAK-M4S45 - Race Grade Upgrade  [SAK-M4S45]

Firm Up the Sakura M4 with the 3Racing SAK-M4S45

Designed for the Sakura M4 chassis, the 3Racing Aluminum Bulkhead (SAK-M4S45) strengthens the car where it matters most. The bulkhead delivers a firmer mounting area that helps preserve accurate suspension alignment even under heavy loads.

Precision for Consistent Setup

Using metal rather than stock materials reduces unwanted flex, so steering and suspension settings remain consistent lap to lap. The result is better repeatability when dialing in camber, toe and ride height.

Made for Track Work

Whether practising or racing, the 3Racing SAK-M4S45 supports more aggressive driving styles by improving chassis stability. It is a practical upgrade for those wanting predictable handling and easier tuning.
