Why magnesium makes a difference

Magnesium is one of the most valued materials in the preparation of competition slot cars. Its stiffness-to-weight ratio is hard to surpass: at just 1.08 g per wheel, the Urano minimises inertia in the wheels, resulting in a more responsive acceleration and direction change. Compared to standard plastic wheels, the difference in track behaviour is noticeable, especially on circuits with fast corners or demanding chicanes.

Assembly and preparation

The fixing system using M2.5 x 3 mm allen screw facilitates assembly and disassembly with common workshop tools. Sloting Plus includes the necessary screws in the bag, so there is no need to search for them separately. It is advisable to tighten with the appropriate torque to avoid damaging the magnesium thread: excessive twisting can compromise the integrity of the wheel in the long term.

When mounting the tyre, we recommend cleaning the surface of the wheel with isopropyl alcohol before applying any adhesive, to ensure a uniform bond without bubbles that could cause imbalance.

Ideal for…

This wheel fits particularly well in club competition cars or in setups aimed at reducing weight at the ends of the axle. The champagne finish also makes it attractive for those who want a distinctive aesthetic touch without sacrificing the performance of magnesium.

Frequently asked questions

What is the difference between a magnesium wheel and a plastic one?

Magnesium is significantly stiffer than plastic, which prevents deformation under load and ensures that the tyre maintains its geometry at all times. Additionally, its lower weight reduces rotational inertia, improving the car's response during acceleration and braking.

What tool is needed to mount the M2.5 allen screw?

An allen (hex) key of 1.5 mm is required. This is a standard size in slot car preparation tools and is usually included in common workshop tool sets.

Can I use these wheels with any slot tyre?

The dimensions 16.7 x 8.5 mm determine compatibility with the tyre. Ensure that the chosen tyre corresponds to that inner diameter and width to guarantee a proper fit without play.

Does the package include the fixing screws?

Yes. Each bag contains 2 wheels and 2 M2.5 x 3 mm allen screws, so you have everything needed for direct assembly.

Does it make sense to use magnesium wheels for recreational use or only in competition?

Although the benefit is more noticeable in competition, any enthusiast looking to explore the preparation of their car will notice the difference. It is an affordable upgrade that adds technical rigor to the assembly.

The Sloting Plus Urano magnesium wheel in champagne finish (SP022321) measures 16.7x8.5 mm and weighs just 1.08 g, making it a top choice for slot car racing preparation. Secured with an M2.5 x 3 mm allen screw, each pack includes 2 wheels and 2 screws — ready to fit and race.
