R/C Suspension Spring 25mm Medium-Soft Yellow for Drift Tuning - Yokomo YOKD119Y  [YOKD119Y]

Overview — 25mm Drift Spring

This coil spring is intended for precise drift setup tuning and broader suspension adjustment on scale R/C cars. Its yellow mark indicates a medium-soft spring rate and the 25mm free length is compatible with numerous compact shock bodies used in 1/10-scale models.

Fit the spring using standard retainers: compress evenly, locate the lower end on its seat, and secure the top retainer so the coils remain centered. Confirm the spring runs true with the shock shaft to avoid lateral binding at extremes of travel.

Tuning approach: make one alteration at a time and use consistent test conditions to assess changes. The medium-soft rate reduces initial stiffness compared with firmer springs, so you may need complementary damping and anti-roll tweaks to preserve handling balance.
