16.9 x 8.2 MG Super-Lightweight Wheel

Less weight, more response: the Super-Lightweight rim from Slot.it in action

The 16.9 x 8.2 MG Super-Lightweight rim from Slot.it (reference SIW16908215M) is a component aimed at those looking to maximise the performance of their car on track. The designation MG refers to its manufacture in magnesium, a material that allows for weight reduction compared to conventional rims while maintaining the structural rigidity necessary for precise driving.

Function and performance

Reducing rotational mass is one of the most effective ways to improve acceleration and car response. By spinning less weight, the motor operates more efficiently and the assembly transmits power to the tyre more directly. In sections of continuous braking and acceleration — slow corners, chicanes, hairpins — the difference compared to a standard rim is clearly noticeable.

The dimensions 16.9 x 8.2 mm place it in a common rear format within Slot.it's tuning range, compatible with the mounting of medium-width competition tyres.

Compatibility and mounting

This rim is designed to integrate into the rear wheel assemblies of Slot.it kits and chassis. Before mounting, it is advisable to check that the inner diameter of the hub fits the rear axle of your setup and that the chosen tyre fits the dimensions 16.9 x 8.2 mm. Slot.it offers specific tyres for this format in its catalogue.

• Material: magnesium (MG), lightweight.
• Dimensions: 16.9 mm diameter x 8.2 mm width.
• Reference: SIW16908215M.
• Typical application: rear axle in competition setups.

Mounting and preparation

To get the most out of a lightweight rim, it is recommended to balance the wheel-tyre assembly before mounting it on the car. A small imbalance can generate vibrations at high speed that negate the advantage of reduced weight. Also, ensure that the tyre is well adhered and centred on the rim before turning, if your setup requires it.

Common mistakes

• Mounting an incompatible width tyre: always check that the profile fits the 8.2 mm width of the rim.
• Not verifying the hub diameter before installation, which can cause play or fitting difficulties on the axle.
• Ignoring the balancing of the assembly, especially on fast circuits where any vibration penalises grip.

Frequently asked questions

What real advantage does a magnesium rim offer over a standard one?

Magnesium is significantly lighter than conventional plastic or aluminium, which reduces rotational inertia. The result is a livelier acceleration and a quicker response to speed changes, particularly noticeable on tracks with many rhythm variations.

Which tyres is this rim compatible with?

It is compatible with tyres designed for a rim width of 8.2 mm and an outer diameter in the range of 16.9 mm. Slot.it has several tyre models for this format; consult their official catalogue to choose the most suitable compound according to the type of track.

Is it suitable for use on Sport track?

Yes. Slot.it is a brand specifically aimed at Sport track, so its entire range of spare parts, including this rim, is designed for that track system. It can also work in other configurations as long as the chassis and axle are compatible with the specified dimensions.

Can I use it on the front axle?

The dimensions 16.9 x 8.2 mm typically correspond to a rear format. For the front axle, there are specific references of narrower width. Always check the Slot.it catalogue to choose the correct size according to the position on the car.

Do I need special tools for mounting?

No special tools are required for basic fitting. If you are turning the tyre to adjust the outer diameter, you will need a suitable wheel lathe for slot. For the rest of the mounting, standard preparation tools are sufficient.

The Slot.it SIW16908215M Super-Lightweight Magnesium Wheel (16.9 x 8.2 mm) is a precision slot car component engineered to reduce rotational mass and improve acceleration response. Ideal for Sport track racing and club-level competition, this magnesium rim pairs with Slot.it's range of competition tyres for a high-performance wheel assembly. A must-have upgrade for serious slot car builders looking to fine-tune their rear axle setup.
