Drivers seeking consistent suspension behaviour will find the Serpent SER401762 Yellow Shock Springs useful. Engineered for 4X EVO compatibility, the springs help keep chassis balance predictable.
The C=5 designation produces a neutral spring response that favours stable cornering without overloading the chassis. That makes it easier to tune damping and sway settings around the springs.
Installing the springs is a simple task for most builders and can be done between runs. Check that preload collars sit evenly and test a few laps to verify handling changes.
