Fine-Tune Motor Height for MR-03 Racing

The Kyosho R246-1321B H Plate Holder is an essential upgrade for Mini-Z MR-03 drivers who want precise control over motor position. It offers selectable motor case heights at -0.5mm, 0mm, and 0.75mm so you can dial in balance and stability for different race conditions.

Race-Focused Height Adjustment

Changing the motor mounting height with the Kyosho R246-1321B alters weight distribution and can improve cornering or straight-line traction depending on setup. These small, repeatable adjustments help you tailor handling without extensive chassis changes.

MR-03 Compatibility and Robust Build

This holder is made to fit the Kyosho MR-03 chassis directly, giving a secure mount and reliable performance. Durable construction stands up to regular track use and the installation is straightforward so you can 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.

How difficult is it to change the motor height with this holder?

Swapping the mount position is a simple procedure using basic tools. The design keeps it quick so you can test different settings between runs.

Which setting works best on smooth indoor tracks?

On smooth indoor surfaces, the neutral 0mm position is a good starting point. From there, small changes toward -0.5mm or 0.75mm will show how balance and traction shift.

Will I need other modifications to use this part?

The holder is designed for direct fit on MR-03. Most users do not need further changes, though some setups may benefit from minor trim or screw length checks.
