Tune Mini-Z MR-03 Response with Kyosho MZW423 Front Springs

The Kyosho MZW423 Front Spring Set brings more controllable front-end feel to the Mini-Z MR-03 line. This collection contains five varieties of soft, short front springs so you can dial suspension stiffness for different track layouts and grip levels.

Compatibility and on-track impact

Compared with the MZW401 springs these are a touch softer and 0.5mm shorter, which helps sharpen turn-in and predictability. Used alongside the MZW415 aluminium upper arm and MZW416 inner tube shock, they help produce a more balanced front end.

Setups and adjustability for club racing

For hobbyists who tinker with setup, the MZW423 pack makes front suspension tuning straightforward. Whether you are running smooth indoor circuits or mixed-surface practice sessions, the range of spring rates lets you quickly optimise grip and stability.
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.

What spring should I try first for tight indoor tracks?

Start with the softest spring in the MZW423 set to increase front grip and reduce understeer on tight layouts. Swap increments until the car turns smoothly without becoming twitchy.

Can I fit these to other Mini-Z uprights?

They are made for MR-03 suspension, but some other Mini-Z models with similar front assemblies may accept them. Check fitment and spring seat depth before racing.

Do I need to change shocks when using softer springs?

You may need to tune damping; pairing softer springs with compatible shocks like the MZW416 inner tube type helps preserve balance and control.
