3DP Plastic Wheel 16.2x8mm. Extreme Design

Extreme lightness and dimensional precision in a 3D-printed wheel for slot racing

The SC-4049Z2 wheel from Scaleauto belongs to the Extreme Design line, a range aimed at drivers seeking every tenth on track. Manufactured using high-quality 3D printing, it combines precise geometry with an extraordinarily reduced weight, two factors that directly influence the car's response and tyre grip.

Technical specifications

• Dimensions: 16.2 x 8 mm
• Weight: 0.3 g (ultra-light)
• Compatible axle: 3/32 (2.38 mm)
• Material: High-quality 3D printed plastic
• Series: Extreme Design
• Reference: SC-4049Z2

Function and performance

Reducing the weight of wheels is one of the most effective improvements that can be applied in the preparation of a competition slot car. By decreasing the rotating mass, acceleration response is improved and braking inertia is reduced, resulting in tighter lap times. At just 0.3 g per unit, the SC-4049Z2 sets a very high standard in this regard.

3D printing allows Scaleauto to achieve geometries with very tight tolerances, ensuring precise centring on the axle and a uniform tyre seating surface. This is especially relevant in competition categories where any imbalance in the wheels can generate perceptible vibrations at high speeds.

Compatibility

This wheel is specifically designed for 3/32 (2.38 mm) axles, the most widely used standard in most slot racing competition chassis on the market. It is compatible with the wide range of tyres available for that inner diameter, allowing the preparer to choose the compound that best suits track conditions and championship regulations.

Assembly and preparation

Assembly is straightforward: the wheel fits directly onto the 3/32 axle and can be secured using the usual gluing method or press fit according to the preparer's preference. To achieve maximum performance, we recommend checking the concentricity of the wheel once mounted and truing the tyre around the axle if the appropriate tool is available. Small preparation details that make a real difference on track.

Ideal for…

This type of wheel fits particularly well in setups aimed at club or regional competition, where regulations allow the use of 3D-printed wheels and seek a balance between cost, lightness, and precision. It is also a very interesting option for hobbyist drivers looking to take a step forward in the preparation of their cars without resorting to more complex machining.

Frequently asked questions

What axle diameter is this wheel designed for?

It is designed for 3/32 axle, equivalent to 2.38 mm, the most common standard in slot racing.

How much does each unit weigh?

Each wheel weighs 0.3 g, making it one of the lightest options on the market in this size.

What advantage does 3D printing offer over other manufacturing processes?

3D printing allows for precise geometries with tight tolerances and shapes that would be difficult or costly to achieve through conventional machining or injection. In the case of Scaleauto, the result is a wheel with very consistent dimensions between units.

Is it compatible with standard silicone or urethane tyres?

Yes, the wheel is compatible with the usual tyres on the market designed for that wheel diameter. The choice of compound will depend on the type of track and running conditions.

Is it sold in pairs or individually?

The available information does not specify the exact number of units per sale unit. Please check the store listing or contact us to confirm before placing an order.

In which position of the car can it be used, front or rear?

The dimensions 16.2x8mm place it in the usual range of rear wheels in many competition chassis, although its specific use will depend on the setup and car model. Verify compatibility with your chassis before installation.

The Scaleauto SC-4049Z2 is a 3D-printed plastic wheel from the Extreme Design series, measuring 16.2x8mm and weighing just 0.3g. Compatible with 3/32 (2.38mm) axles, it is a top choice for slot car racing enthusiasts looking for lightweight wheels with precise dimensions. Ideal for club-level competition and serious slot car preparation.
