Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How often should I replace race springs?

Replace springs when you notice loss of free length, inconsistent lap to lap handling, or visible damage; frequency depends on use but check them regularly.

Do these springs change dampening feel or only spring rate?

Springs alter the spring rate and response; dampening is set by shock oil and pistons, so adjust both when refining overall suspension behavior.

Can I use these springs for both practice and race days?

Yes, they are suitable for repeated practice and race sessions; carry spares and inspect after heavy use to ensure consistent performance.

Any tips for matching springs to tyre choices?

Harder compound tyres may need firmer springs to maintain balance, while softer tyres often pair with slightly softer springs to improve mechanical grip.
