3Racing Sakura Zero Damper Spring M1.5 x 21 (6.5) - SAK-49/21650 Racing Spec  [SAK-49/21650]

Race-Oriented Spring Upgrade

The 3Racing Sakura Zero Damper Spring M1.5 x 21 (6.5) - SAK-49/21650 provides a consistent spring rate suited to methodical setup changes on Sakura Zero cars. These springs are intended for drivers who prioritise repeatable handling adjustments.

Consistent Rate for Tuned Damping

Engineered to offer even coil response, the springs support predictable shock movement and help maintain chassis balance when changing oil viscosity or ride height. The M1.5 x 21 dimensions align with Sakura Zero damper geometry.

Material Stability and Longevity

Manufactured with attention to winding tolerance and material finish, the 3Racing springs resist rate drift over many cycles. That stability assists precise setup comparisons during testing.

Optimise Setup in Small Steps

Use these springs to methodically alter roll stiffness and transient response. Incremental spring changes combined with damping and tyre adjustments yield measurable performance differences on track.
