Competition grade reinforcement for the Sakura D4 chassis

The 3Racing Sakura D4 Bulkhead SAK-D404 is aimed at drivers who demand repeatable chassis behaviour for setup work and race conditions. It reduces unwanted flex to keep suspension geometry predictable during cornering and weight transfer.

Performance oriented features

  • Chassis integration: Aligns with Sakura D4 mounting points to preserve intended suspension geometry and simplify setup changes.
  • Durability focus: Built to withstand routine racing stresses while providing a stable platform for adjustments.
  • Setup benefits: A stiffer bulkhead sharpens steering feel and makes small tuning changes more effective for lap time improvements.

They are awesome! You guys are awesome! Had what i needed and they arrived in a timely manner. No damage, etc. Would buy again, would recommend.

How does the SAK-D404 affect torsional rigidity?

The SAK-D404 increases local chassis stiffness which reduces torsional deflection, helping to keep suspension pickup points aligned under load.

Should spring rates be changed after fitting?

In many cases slightly softer springs or altered anti-roll settings will complement the increased chassis rigidity to regain desired compliance.

Is the bulkhead suitable for setup development work?

Yes, the SAK-D404 provides a more stable baseline, making it easier to evaluate suspension and tyre adjustments during setup sessions.
