Dial In MR-03 Steering with Kyosho MZW445B

The Kyosho MZW445B caster setting upper arm set is built for the MR-03 chassis and gives racers a simple way to tune steering balance. Choose from three caster positions - 1 degree, 2 degrees, or 3 degrees - to tailor turn-in and mid-corner stability without changing other suspension parts.
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 will a higher caster setting change steering feel?

Increasing caster generally adds straight-line stability and more self-centering at the wheel, while lower caster can make initial turn-in quicker. Try small steps between 1, 2 and 3 degrees to find the best balance for your driving style.

Is the Kyosho MZW445B difficult to fit to an MR-03?

Installation is straightforward with common hobby tools. Follow the chassis manual for removal of the upper arms and swap in the MZW445B components, then check alignment and steering geometry after fitting.

Which driving conditions suit each caster angle?

Use lower caster for tight, quick-turn tracks where turn-in is priority, and higher caster on faster layouts where stability and corner exit traction matter. Tune with tyre choice and toe settings for best results.
