FUCHS type wheel x2 units

FUCHS-style wheels from SRC: the classic finish your slot car deserves

The FUCHS-style wheels from SRC (reference SP10021) are a faithful reproduction of the iconic five-petal design, crafted from bicolor aluminium and precisely calibrated to ensure a vibration-free fit and stable performance on track. They are presented in a pack of 2 units, with all necessary mounting materials included.

Technical specifications

• Material: calibrated bicolor aluminium.
• Diameter: 15.8 mm.
• Weight: 1 g (tolerance ± 0.3 g), lightweight to reduce rotational inertia.
• Central hub: double hole for M2.5 grub screw metric 2.5 x 0.45 x 3.
• Length of grub screw: 6 mm.
• Hub diameter for axle: 2.38 mm.
• Wheel section width: 8.30 mm.
• Wheel bead: 0.8 mm.
• Pack contents: 2 wheels + 6 grub screws + 1 allen key.

Function and performance

The calibrated bicolor aluminium of these wheels ensures very tight concentricity, which translates directly into smooth and stable running. The lightweight design at 1 g is a significant factor: the less a wheel weighs, the less inertia the motor must overcome when accelerating or braking, improving the car's response during changes of pace.

The hub with double hole allows for secure tightening on the axle thanks to the M2.5 grub screws, which fit perfectly into the 6 mm holes. The combination of a 0.8 mm bead and a section width of 8.30 mm provides a solid base for the tyre, promoting uniform contact with the track.

Installation and preparation

Installation is straightforward: insert the 2.38 mm axle into the central hub, position the wheel at the desired point, and tighten the grub screws with the included allen key. It is advisable to check the perpendicularity of the wheel relative to the axle before final tightening, and once the tyre is mounted, perform a light sanding on a grinding bench to ensure the exact rolling diameter.

The pack includes 6 grub screws, which comfortably covers both wheels and allows for spare parts in case any are damaged during adjustment.

Ideal for…

These wheels fit perfectly in slot car preparation projects where a visual finish close to classic five-petal designs is sought, without compromising technical precision. They are a common choice for both club racing builds and display builds where the aesthetic detail of the wheel is part of the final result.

Common mistakes to avoid

• Tightening the grub screws without checking alignment: a slight misalignment before tightening can cause vibration at high speeds. Always check concentricity before final fixing.
• Mounting the tyre without truing: although factory calibration is precise, a light pass on the truing bench after mounting ensures the exact diameter and maximum grip.
• Confusing hub diameter: these wheels are designed for 2.38 mm axles. Check your axle measurement before purchasing.

Frequently asked questions

What axle diameter are these wheels designed for?

The central hub is sized for 2.38 mm axles, which is a standard measurement in 1/32 scale slot car preparations.

Does the pack include the grub screws and allen key?

Yes. Each pack of 2 wheels includes 6 M2.5 x 0.45 x 3 grub screws and 1 allen key, allowing you to complete the installation without the need for additional materials.

Is it necessary to true the tyre after mounting?

It is not strictly mandatory, but it is highly recommended. A pass on the truing bench after mounting the tyre ensures that the rolling diameter is perfect and uniform, improving stability and grip on track.

What advantage does the lightweight design at 1 g offer?

Reducing the weight of the wheel decreases rotational inertia, which enhances the car's response during acceleration and braking. This is especially noticeable on tracks with many fast corners.

Are they compatible with any slot car?

Their compatibility depends on the axle diameter (2.38 mm) and section width. Check the measurements of your car or chassis before placing an order to ensure a correct fit.
