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

Upgrade the Sakura M4 with a 3Racing SAK-M4S45 Bulkhead

The 3Racing Aluminum Bulkhead (SAK-M4S45) is tailored for the Sakura M4 chassis to replace softer components and give a firmer structure. This helps keep suspension pick-up points true, supporting reliable handling through technical sections.

Robust Metal Design

Switching to an aluminium bulkhead reduces chassis distortion during heavy cornering and impacts, maintaining correct suspension alignment. This stability aids predictable turn-in and steadier mid-corner balance.

Suited to Competitive Driving

For drivers chasing consistent lap times, the 3Racing SAK-M4S45 provides a clear upgrade pathway, improving chassis rigidity and making setup adjustments yield more noticeable changes.
