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 do I choose between the 1, 2 and 3 degree settings?

Consider track speed and required steering precision. Use 1 degree for nimble responsiveness, 2 degrees for a neutral balance, and 3 degrees when you want stronger straight-line stability and return. Run short tests to decide what suits your setup.

Will changing caster affect steering trim or servo workload?

Altering caster can change steering return feel, which may require minor trim adjustments. Check servo centring and steering travel after any change to ensure neutral handling.

Any maintenance advice after fitting the MZW445B?

After installation, inspect mounting screws and ball joints regularly and confirm there is no binding in the steering. Periodic checks keep the geometry consistent and handling predictable.
