Racing Grade Rear Bulkhead for Sakura D3

The 3Racing SAK-D316/PK aluminium rear bulkhead is produced to reinforce the Sakura D3 CS SPORT chassis with a low-tolerance metal replacement. Intended for racers seeking consistent flex characteristics, this component strengthens the rear mount area while preserving OEM geometry.

Precision and Track Consistency

Manufactured with a focus on dimensional accuracy, the aluminium unit reduces unwanted chassis movement under load, helping suspension settings behave predictably during aggressive driving and lap-to-lap tuning.

Plug-In Fit for Quick Setup Changes

The bulkhead is designed to accept stock Sakura D3 CS SPORT fasteners and drivetrain parts without modification, allowing fast installation and minimal downtime between test sessions.

How does this bulkhead alter chassis flex for tuning?

By increasing rear stiffness it narrows the flex band at the rear, which can tighten rotation and improve response to damper and anti-roll bar adjustments.

Is any shimming required to maintain pinion alignment?

No additional shims are typically needed since the part preserves stock mounting points, but confirm pinion mesh during refit to avoid gear wear.

Recommended maintenance for race use?

Inspect mounting faces for burrs and check fastener torque regularly; reapply medium strength thread locker if you run frequent heat cycles.
