Kyosho MZW309 Precision Motor Mount for MR-03 LM

The Kyosho MZW309 Aluminum Motor Mount is a practical upgrade for MR-03 LM owners who want cleaner weight distribution and sharper traction. Precision machining delivers a tight fit and helps reduce unwanted vibration while supporting the LL (98mm) wheelbase for straightforward Mini-Z integration.

Track-Focused Stability and Control

This mount improves stability at speed by evening out left-right mass, which helps the car plant through corner exits. The accurate tolerances of the MZW309 also complement damping setups, and when used with the MZW310 Inner Tube Roll Shock Set the chassis response becomes noticeably more consistent.

Fitment Notes and Simple Installation

The MZW309 is made to suit the Kyosho MR-03 LM chassis and the LL wheelbase layout. Installation is designed to be user friendly so hobbyists can swap mounts without complex modifications and get back on track quickly.
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 this mount fit other Mini-Z chassis aside from MR-03 LM?

The MZW309 is tailored for the MR-03 LM and LL (98mm) wheelbase. Other Mini-Z frames may require spacers or alteration, so check measurements before fitting.

How does the aluminum mount affect handling on carpet or foam tracks?

Aluminum evens out weight transfer and reduces flex compared to stock plastic mounts, which typically tightens turn-in and improves mid-corner grip on low-friction surfaces like carpet and foam.

Do I need different screws or hardware to install the MZW309?

Most installs use the original mounting hardware, but inspect screw lengths and thread engagement during installation. Replace any worn fasteners and use threadlock if you run on rough layouts.
