Kyosho MZW416B-02 Mini-Z MR-03 Adjustable Caster Arms  [KY-MZW416B-02]

Improve Steering Response with Kyosho MZW416B-02

If you run an MR-03 and want finer control over front-end behaviour, the Kyosho MZW416B-02 adjustable caster arm kit fits inner tube shock layouts and lets you tune caster for different grip levels. It gives you straightforward control over steering character.

Three Distinct Angle Choices

The set contains three pairs of caster arms offering 1, 2 and 3 degree positions so you can experiment with sharper turn-in or a calmer balance midcorner. These options suit testing across slick indoor floors and higher grip surfaces.

Built to Match MR-03 Geometry

With dimensions matching the MR-03 chassis points, the arms install cleanly and let you swap settings between sessions. Their fit keeps suspension geometry consistent while you evaluate handling changes.
