Fine Tune MR-03 Cornering with Kyosho MZW423 Front Springs

The Kyosho MZW423 Front Spring Set is a simple way to tweak handling on Mini-Z MR-03 cars. The set includes five soft, short front springs so you can experiment with different stiffness levels to suit track conditions.

Why these springs change handling

Compared to the MZW401 type these springs are a bit softer and 0.5mm shorter, producing crisper steering feedback. When used with the MZW415 aluminium upper arm and MZW416 inner tube shock the front end gains better response and control.

Easy tuning for better lap times

For tuners who chase lap time gains, the MZW423 group offers quick swaps between rates to find the best balance of grip and stability on both fast and technical circuits.
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.

Will these reduce understeer?

Yes, selecting a softer front spring from the MZW423 set can reduce understeer by allowing the front tyres to maintain a better contact patch during turn entry.

Do they require new spring cups?

They fit standard MR-03 spring seats, but verify cup fit and preload so springs sit correctly and do not bind at full travel.

How do I test changes on track?

Make one change at a time and run a few rhythm laps, noting turn-in, mid corner balance and exit traction to judge each spring rate.
