Race Oriented Upper Deck Engineering for the Sakura Ultimate

The 3Racing SAK-U414_B is a race focused graphite upper deck engineered to refine chassis flex characteristics on the Sakura Ultimate platform. The 2.0mm thickness is selected to tighten torsional response while preserving usable compliance for track conditions common in competitive classes.

Precision Materials and Setup Impact

Manufactured from high modulus graphite, this deck reduces unwanted bending in critical load paths and improves feedback through the steering system. In stock configurations the SAK-U414_B helps produce repeatable handling, which makes setup changes more predictable during tuning sessions.

Integration and Tuning Advice

Designed to align with standard Sakura Ultimate mounting geometry, the 3Racing SAK-U414_B installs without major modification. For competitive use, pair the deck with incremental shock valving and antiroll bar adjustments, and log lap time comparisons to verify gains under race conditions.

How does deck stiffness influence corner entry under braking?

Increasing upper deck stiffness reduces mid chassis compliance, which can sharpen turn in under braking. To control entry behaviour, fine tune front roll stiffness and brake bias incrementally.

Should I alter diff tuning when fitting the SAK-U414_B?

A stiffer deck can change load transfer and diff feel; consider small changes to diff oil weight or preload to maintain consistent drive out of slow corners.

What telemetry or notes should I record after upgrade?

Record lap times, sector consistency, steering response, and tyre temperatures. Compare these metrics before and after fitting the SAK-U414_B to quantify handling changes for further tuning.
