Race-Oriented Rear Arm for Sakura Ultimate

The 3Racing Sakura Ultimate Rear Suspension Arm SAK-U319 is a competition-focused graphite composite component that increases torsional rigidity at the rear of the chassis. Manufactured to support precise setup changes, this arm helps maintain alignment under load and improves the consistency of rear traction during aggressive driving.

Technical Features and Tuning Notes

  • Material: CNC-grade graphite composite for a controlled stiffness profile suited to tuning adjustments.
  • Compatibility: Designed to match Sakura Ultimate mounting geometry for predictable fitment.
  • Performance: Reduces unwanted compliance, aiding sharper transition and improved corner exit stability.
  • Durability: Constructed to withstand repeated race use while retaining critical mounting integrity.

How does this arm affect rear roll characteristics?

The increased stiffness from the graphite composite reduces lateral compliance, which typically lessens rear roll and provides a more immediate response to throttle and steering inputs.

Any setup tips for optimising handling with this arm?

Start with stock geometry and evaluate rear toe and shock rates; small changes to damping and toe-in can help balance the firmer rear feel.

What inspection points are critical after a hard impact?

Check mounting hole roundness, look for delamination or cracks in the composite, and confirm fastener torque to preserve setup accuracy.
