Technical Notes for Sakura Zero Spring Setup

The 3Racing SAK-49/21475 damper spring set is specified for the Sakura Zero and intended for detailed setup work. The 1.5mm wire diameter and 21mm length produce a consistent mechanical response suitable for tuning spring rates without changing shock geometry. Use these springs when refining balance between front and rear to control roll characteristics and bite through corners.

How should I sequence spring tests during setup

Test one variable at a time: install the SAK-49/21475 springs front or rear, run consistent laps, then adjust damping to match. Log each change to quantify handling shifts.

Do these springs require damper oil changes

Matching damper oil viscosity to spring stiffness is recommended; firmer springs generally work with slightly heavier oil to maintain control over stroke and rebound.

What fitment checks should I perform before racing

Verify spring seating, collar clearance and that spring length suits your shock travel. Confirm no coil bind and ensure symmetry left to right for consistent handling.
