Lightweight Magnesium Wheels 16.5x10mm for 2.3 axle

Sideways Magnesium Wheels: Less Weight, More Agility in Every Corner

When tuning a competition slot car, every gram counts. The Sideways SWW16510MG wheels are made from magnesium and designed with a lightweight profile to minimise rotating mass. The result is a more responsive acceleration, lower inertia during braking, and a more direct and predictable handling feel.

Features and Function

• Material: magnesium, lighter than conventional aluminium and with good structural rigidity.
• Size: 16.5 mm diameter × 10 mm width.
• Compatible axle: 2.3 mm axle.
• Lightweight design: the internal machining reduces weight without compromising strength or concentricity.

Track Performance

Replacing standard wheels with lightweight magnesium ones is one of the most common steps in serious slot car preparation. By reducing rotating inertia, a cleaner acceleration is noticeable from chicanes and greater ease in controlling oversteer in fast corners. Combined with well-adhered and concentric competition tyres, these Sideways wheels contribute to a balanced and predictable setup.

Compatibility and Installation

Designed for a 2.3 mm axle, it is essential to check the axle diameter of your car before installation. The size 16.5×10 mm makes them suitable for rear configurations in 1/32 scale where a medium-wide tyre is desired. Installation follows the usual process: fitting to the axle, checking concentricity on the lathe, and adhering the tyre with the appropriate adhesive.

Common Mistakes

• Fitting magnesium wheels without checking concentricity: a slight wobble negates the advantages of the material.
• Using aggressive adhesives that attack magnesium: always opt for specific cyanoacrylate for wheel-tyre bonding.
• Confusing axle diameter: these wheels are for 2.3 mm; if your axle is 2.38 mm or 3 mm, you will need a different reference.

Ideal for…

Preparers and club racers competing in categories where weight and dynamic response make a difference. Also for demanding enthusiasts looking to extract maximum performance from their Sideways cars or any other model that uses a 2.3 mm axle and accepts this wheel size.

Frequently Asked Questions

What real advantage does magnesium have over aluminium in a slot wheel?

Magnesium is between 30% and 35% lighter than aluminium for an equivalent volume. In a wheel, this directly translates to less rotating mass, which improves acceleration and makes it easier to control the car during braking and cornering.

Are these wheels compatible with any 16.5 mm tyre?

In principle, yes, as long as the tyre has the appropriate inner diameter for the wheel. We recommend checking with the tyre supplier that the wheel size 16.5×10 mm is correct for that specific model.

What axle diameter are they designed for?

For a 2.3 mm axle. If your car has a different axle diameter (2.38 mm or 3 mm, for example), these wheels will not fit correctly and you will need a different reference.

Do I need to balance or turn the wheels before using them?

Although the Sideways magnesium wheels have careful machining, it is always advisable to check concentricity once mounted on the axle and to lightly turn the tyre if any wobble is detected. This is standard practice in competition preparation.

How many wheels are included in the SWW16510MG reference?

The available information does not specify the exact number of units per blister. We recommend checking the product description in-store or contacting our team to confirm before placing an order.
