This Yokomo 25mm spring is intended for R/C drift suspension use, offering a medium-hard stiffness that balances support and compliance. It gives firmer behaviour than softer springs while still allowing controllable slide dynamics.
To install, seat the spring correctly on the shock shaft and check the end-cap position and preload for your shock assembly. After installation, re-check ride height and camber change under compression and observe damping interaction to assess the overall handling change.
Using a medium-hard spring like this helps limit excessive squat and body roll during throttle-applied slides, improving stability through corner exits. The pink mark makes it simple to distinguish this rate from other springs in your kit.
