The Kyosho IFS001-7515 is a 70mm red big shock spring created to refine damping and give more consistent handling feedback. It is a sensible upgrade for modelers focusing on predictable chassis behaviour.
This spring complements a variety of chassis arrangements and is ideal for adjusting roll and traction balance without swapping major components. It is a go-to option for drivers tuning corner entry and mid-corner stability.
Fitting the Kyosho IFS001-7515 is simple: ensure the shock can accept a 70mm spring, change the coils, then test and adjust preload and oil to suit track conditions. Regular checks and cleaning help preserve consistent performance.
