Wheel 15.8 x 10.2 Mg

Slot.it Magnesium Wheel: Less Weight, More Response in Every Turn

The SIW15810215M wheel from Slot.it measures 15.8 mm in diameter by 10.2 mm in width and is made of magnesium (Mg), one of the most valued materials in slot preparation precisely for its very low density. By reducing the rotating mass, the car reacts more agilely to changes in acceleration and improves stability in corners.

This reference is the direct successor to the old WH1184-Mg, so if you were already familiar with that code, you can find it here with the current nomenclature of Slot.it.

Main Features

• Dimensions: 15.8 mm in diameter × 10.2 mm in width.
• Material: magnesium, for minimal rotating mass.
• Current reference: SIW15810215M (formerly WH1184-Mg).
• Brand: Slot.it, a leading manufacturer for Sport track competition.

Function and Performance

In competitive slot racing, every gram removed from the rotating parts has a direct effect on acceleration and braking. Magnesium achieves this with sufficient structural rigidity to withstand track use without deforming. The result is a wheel-tyre set that responds more cleanly to the controller's commands.

Compatibility and Installation

Slot.it designs its wheels to fit with the axles and tyres from its own catalogue. To ensure exact compatibility with your chassis or axle, consult the technical data sheet from Slot.it or the preparation catalogue of your set. If you have any doubts, Ministry of Hobby can help you find the correct combination.

Ideal for…

• Tuners and competitors looking to minimise rotating inertia.
• Club setups where the regulations allow magnesium wheels.
• Enthusiasts wanting to explore the technical preparation of their slot cars.

Considerations

Magnesium is a more delicate material than plastic or aluminium against strong impacts. Handle it carefully during installation and avoid over-tightening when securing the tyre. Careful preparation significantly extends the lifespan of the wheel.

Frequently Asked Questions

What advantage does magnesium have over plastic in a slot wheel?

Magnesium is significantly lighter than conventional plastic, which reduces the rotating mass. This translates into sharper acceleration and a more precise response when cutting power during braking.

Is the SIW15810215M the same wheel as the WH1184-Mg?

Yes. The reference WH1184-Mg is the previous designation of this same product. Slot.it updated its nomenclature system, and the wheel is now called SIW15810215M, with no changes to its physical characteristics.

Which Slot.it tyres is this wheel compatible with?

Slot.it designs its wheels and tyres to work together within its catalogue. We recommend consulting the compatibility chart from Slot.it or contacting us to confirm the appropriate tyre for your application.

Can I use it in club competition?

It depends on your club's regulations. Magnesium wheels are allowed in many Sport track categories, but some local regulations limit materials. Check this before installation.

The Slot.it SIW15810215M is a magnesium wheel measuring 15.8 x 10.2 mm, formerly known as WH1184-Mg. Designed for slot car racing on Sport track systems, it minimises rotational mass for sharper acceleration and improved handling. A popular choice among club racers and slot car tuning enthusiasts looking for lightweight wheel options compatible with Slot.it axles and tyres.
