3Racing Sakura Ultimate SAK-U109/WO Graphite Main Chassis Upgrade  [SAK-U109/WO]

Stiffness and control from the 3Racing SAK-U109/WO graphite chassis

The 3Racing Sakura Ultimate Graphite Main Chassis, model SAK-U109/WO, is an upgrade aimed at club and track racers who want a tougher, more responsive platform. Machined graphite construction raises rigidity while keeping overall mass low, helping drivers maintain stable lines under load.

Track-focused rigidity and handling improvements

Built for the Sakura Ultimate platform, this graphite chassis increases torsional stiffness to reduce flex in high speed sections and through tight corners. The reduced flex improves steering predictability and helps keep suspension geometry consistent, which leads to steadier lap times and fewer mid-corner surprises.

Graphite benefits for competitive setups

Graphite provides a strong strength-to-weight profile that most racers prefer for fine-tuning balance. The SAK-U109/WO helps damp small impacts while preserving chassis stiffness, giving a more controlled feel over bumpy sections and improving traction on technical circuits.

A practical choice for racers upgrading a Sakura Ultimate, the graphite main chassis balances durability and responsiveness for improved on-track performance.
